A Guide to Understanding Indoor Air Quality Solutions

Is Indoor Air Quality Important?

The American Lung Association® lists poor indoor air quality (IAQ) as a serious problem facing homeowners due to today's tighter homes. Outside air stays out, while air pollutants, excessive humidity, and/or overly dry conditions stagnate the indoor air over time.

Allergen Concerns

Pollen, mold spores, and other common allergens, as well as bacteria and viruses in indoor air, can be an issue.

Comfort Concerns

High humidity can keep a home damp and sticky, while excessive dryness can crack woodwork and antiques, or create static electricity and dry skin. In addition, microscopic particles in the air slowly stain walls, ceilings, furniture, drapes, and carpets, making a home feel less welcoming.

Offer Solutions

Homes need properly balanced indoor air quality. Use the solutions in this guide to help your customers improve comfort in their homes.

Three Ways To Improve Indoor Air Quality

Source Control

Eliminate air pollutants before they enter the home. For example, some homeowners may not allow smoking or pets in the home, but that isn't practical for most people. Instead, stop contaminant problems before they start by installing whole-house humidifiers, dehumidifiers, ventilators, and UV treatment systems.

Dilution

Out with the old air, in with the new. This can be accomplished by opening windows, but that wastes heating and cooling energy. Energy-efficient ERV and HRV ventilation systems exchange indoor air for outdoor air while recovering most of the energy used to heat or cool the air being exhausted. This treated fresh air can then be efficiently further conditioned by an air cleaner, dehumidifier, and UV treatment system.

Reduction

As air circulates in the home, the number of particulates are reduced during each pass through air cleaners installed just ahead of the heating and cooling equipment. This helps maintain a steady flow of cleaner air.

Understanding Airborne Particles

Every cubic foot of air you breathe carries a mixture of millions of airborne particles so small you could fit 749 of them in the eye of a needle! These include:

Pollen and spores
Human skin flakes
Candle soot
Infiltrating dust
Viruses, bacteria, and fungi
Pet dander
Tobacco or wood smoke
Cooking smoke and airborne grease
Radon gas seeping through the walls and foundations
Chemical fumes and volatile organic compounds generated by household cleaners

Air Filtration and Performance

Use air filtration efficiency ratings and the importance of maintaining airflow as the filter gets dirty to help homeowners compare air-cleaning options.

Measuring Air Filtration Performance

Every time the furnace or air conditioner blower operates, it circulates air through the ductwork. The force it must overcome to move this air is called “static pressure.” Because air cleaners are designed to capture particles, they present a barrier to airflow. This is important because air cleaner efficiency ratings can be related to static pressure and pressure drops. Achieving an apples-to-apples comparison between different air cleaners can be a difficult task because manufacturers may measure efficiency at different airflows and pressures.

Types of Efficiency Testing

Air filtration efficiency depends on the type of air cleaner used, and the type, number, and size of the particles in the air stream. The lowest ratings are typically found on ordinary throw-away fiberglass filters. Resideo's electronic air cleaner has one of the highest ratings.

Fractional Efficiency Testing measures the efficiency of media filters and electronic air cleaners by size of particle captured. The higher the test figure, the higher the efficiency.
Minimum Efficiency Reporting Value (MERV) is based on Fractional Efficiency Testing and measures the efficiency of media air filters and cleaners that have been in service for a period of time. The higher the media MERV rating, the better the efficiency over the life of the filter. See page 10 for more detail.
Weight Arrestance Testing measures the weight of particles trapped by the air cleaner and is typically used for filters that have a MERV below 4. A small fraction of all particles (10%) account for 99% of the weight of all particles in the air. These heavy particles tend to settle from the air before reaching an air cleaner.
Initial pressure drop measures the decrease in air pressure across new media filters or recently cleaned electronic air cleaners. The lower the pressure drop, the better the airflow in the HVAC system.
Resideo air cleaners are tested using the Fractional Efficiency Testing, MERV Testing, and Initial Pressure Drop measurements. Weight Arrestance Testing does not differentiate high-efficiency filters.

Diagram Description: A line graph titled "Removal Efficiency (at 0.3 to 1.0 microns)" shows removal efficiency on the Y-axis (0-90%) and Filter Loading (Time) on the X-axis (0, 1 YR, 2 YR, 3 YR). Two lines represent "Electronic Air Cleaner" (Cell Cleaned and Cell Not Cleaned) which remain high. Two other lines represent "Filter Replaced" and "Filter Not Replaced" for a "MERV 10 Media Air Cleaner" which start lower and decrease over time.

Our electronic air cleaners stay highly efficient between washings, and cause much less pressure drop when dirty.

Filter Efficiency

Diagram Description: A bar chart titled "Initial Efficiencies" shows "Fractional Efficiency (%)" on the Y-axis (0-100%) and "Particle Size (microns)" on the X-axis. Multiple colored lines represent different filter types (FC200, PopUP, FC100, F300E at 500 fpm, F300E at 300 fpm, 1" Filter), illustrating their efficiency across various particle sizes.

Filter Life

Diagram Description: A line graph titled "Pressure Drops as Filter Gets Dirty" shows "Pressure Drop (in. w.c.)" on the Y-axis (0-0.5) and "Dust Fed (g)" on the X-axis (0-90, Clean to Dirty). Multiple colored lines represent different filter types, showing how pressure drop increases as the filter gets dirty.

Growing Demand

Consumer demand for air cleaners has been on the rise in recent years. According to the Environmental Protection Agency (EPA), indoor air can be 2 – 5 times more polluted than outdoor air. Informing homeowners of how filtered air can increase overall comfort is an important selling point.

Signs That A Home Needs Air Filtration

Typical Installations

An Electronic Air Cleaner or Media Filter should be installed where maximum air circulation is passing through the HVAC system. Resideo offers air cleaners for return duct or return grill installations. For the most efficient air cleaning, spread airflow evenly across the face of the media, and choose a location that is readily accessible for filter maintenance.

Diagram Description: Three illustrations show typical installations of air cleaners/filters within HVAC systems. One shows a filter installed in a return duct grill. Another shows a filter installed in a return duct. The third shows a larger whole-house air cleaner unit connected to ductwork.

Central System Air Cleaners and Filters

Central system air cleaners and filters are generically categorized by:

Basic Furnace Filters

Basic Furnace Filters protect the furnace from bulk dust but do little to remove smaller particles from the air. They come standard with most HVAC systems.

High-Efficiency Particulate Air (HEPA) Filters

High-Efficiency Particulate Air (HEPA) Filters use deeply folded media to trap a minimum of 99.97% of 0.3 micron particles passing through the filter. Due to air-flow restrictions, HEPA filters do not get installed in a return duct and are typically portable, standalone air-cleaners.

Beware of manufacturers who use terms like "HEPA-style" or "HEPA-like" filters as they may only be "close to” HEPA efficiencies or achieve HEPA efficiencies by circulating air through the filter numerous times.

Media Filters

Media Filters filter the air using webs of polypropylene fibers. Resideo offers several media air cleaners and replacement filters, including space and time-saving products like the PopUP™ media replacement filter. The PopUP™ simplifies installation and maintenance with a design that collapses down for space-saving shipping and self-assembles without the need for combs, pleat spacers, or end caps.

Electronic Air Cleaners

Electronic Air Cleaners electrically charge and collect airborne particles on a collection grid. The Honeywell Home F300 EAC is up to 30 times more efficient at capturing airborne particles from the air passing through the filter compared to a standard one-inch filter. Its collection grid section offers the most surface area available for charged-particle collection, and it maintains high efficiency over time by increasing voltage based on the amount of particles collected.

Diagram Description: Three stages illustrate the process of electronic air cleaning. Stage 1 (Pre-Filter Screen) captures large particles. Stage 2 (Charging Station) uses electronically charged wires to zap particles. Stage 3 (Collection Station) uses electronically charged plates to attract particles like magnets. The result is cleaner air circulated back through the home.

Honeywell Home Replacement Filters

Honeywell Home replacement filters come in a wide variety of sizes and styles to fit nearly every application. For long-lasting, high efficiency performance that doesn't compromise airflow, advise your customers to stick with quality Honeywell Home filters.

What is MERV?

MERV (Minimum Efficiency Reporting Value) is a measure of filter efficiency. The MERV value takes information on the efficiency of the filter against a range of particles from coarse (such as pollens) to fine (such as smoke), then boils it down into one easy-to-understand number. The MERV number can be used to compare filters made by different manufacturers as long as testing conditions, such as air speed, are the same.

Filter Category	Airborne Contaminants Targeted*	Equipment Protection	Air Treatment Level
MERV 1 to 4 Coarse fiber filter	Pollen, airborne dust mite debris, carpet and clothing fibers	Minimal	Minimal
MERV 5 to 8 Standard household filter	The above plus: Mold and plant spores	Basic	Basic
MERV 9 to 12 Premiere household filter	The above plus: Auto emissions, airborne lead dust, airborne coal dust	Basic	Improved
MERV 13 to 16 Hospital grade	The above plus: Certain bacteria, tobacco smoke, sneeze particles, cooking oil	Improved	Superior

Ventilating For Today's Homes

Modern building construction and codes require modern ventilation. Honeywell Home whole home ventilation systems efficiently bring in fresher air while driving out stale air. Highly versatile, they're ideal for both new construction and retrofit projects.

Diagram Description: Two diagrams compare ventilation in homes built before 1985 versus today's construction methods. Pre-1985 shows exfiltration and infiltration. Today's construction highlights features like housewrap, continuous air/vapor barrier, low leakage windows, sealed combustion furnace, and sealing gaskets.

Typical Installations

Honeywell Home Energy and Heat Recovery Ventilation (ERV and HRV) systems are designed for installation versatility and integrate with existing HVAC equipment or can function as a standalone system.

For ventilation installation, the air duct and damper must be installed between the outdoors and the return side of the HVAC system. The ventilator can be controlled in different ways. A standalone control can be installed in the same room as the ventilator, or control can be handled through an IAQ thermostat.

Diagram Description: Three diagrams illustrate typical ventilation system installations: Typical Attic Installation, Typical Basement Installation, and Typical HRV/ERV Installation, showing placement of the ventilation unit and controls within a home's structure.

ASHRAE Standard 62.2 for Ventilation

ASHRAE Standard 62.2 “defines the roles of and minimum requirement for mechanical and natural ventilation systems and the building envelope intended to provide acceptable indoor air quality (IAQ) in low-rise residential buildings.” (ASHRAE 62.2)

Ventilation for ASHRAE 62.2 May Be Met By Any of the Following:

Exhaust Ventilation

Negative pressure draws fresh air from an unknown source.
Fresher air may come through structure, garage, etc.
Must have make-up air for combustion products.

Supply Ventilation

Positive pressure pushes stale air out of the home.
Fresher air enters home from a known source.
Fresher air can be conditioned before entering the living space.
Stale air may pass through the structure.

Balanced Ventilation

Net zero pressure differential in home.
Outdoor air comes from a known source.
Fresh air can be conditioned before entering the living space.

Helping Homeowners

Educating homeowners on the need to exchange air will help them understand that whole home ventilation is far more effective than portable units. Whole home ventilation is quieter, has a higher capacity, and is more cost-effective.

Signs That A House Needs Ventilation

Excessive dust (house under negative pressure)
Overly humid
Lingering odors from cooking

Sizing a Ventilation System According to ASHRAE 62.2:

According to ASHRAE Standard 62.2, the required amount of outdoor air to be continuously introduced into the home is:

Qfan = 0.01Afloor + 7.5(Nbr + 1)

Where: Qfan = fan flow rate, CFM; Afloor = floor area, ft²; Nbr = Number of bedrooms; not to be less than 1.

Floor Area (ft²)	Bedrooms
	0-1	2-3	4-5	6-7	>7
< 1500	30	45	60	75	90
1501-3000	45	60	75	90	105
3001-4500	60	75	90	105	120
4501-6000	75	90	105	120	135
6001-7500	90	105	120	135	150
> 7500	105	120	135	150	165

There are also provisions in ASHRAE 62.2 that allow ventilation to be delivered on a non-continuous basis, providing maximum output at a fraction of the time. ENERGY STAR, Environments for Living (EFL), and many ventilation codes in the US and Canada require homes to install ventilation per the ASHRAE 62.2 Standard.

All Resideo ventilation controls have built-in programming to ventilate according to ASHRAE 62.2, making it easy to meet this code and pass inspection.

Resideo Ventilation

Help homeowners understand their options for the best balance of energy savings and ventilation control.

Honeywell Home Energy Recovery Ventilators (ERV) and Heat Recovery Ventilators (HRV) efficiently bring fresher outdoor air into the home by recovering up to 70% of the exhausted air's sensible heat as well as some latent heat. As stale air is exhausted outside through the ventilator, heat is transferred from one air stream to the other as the air passes through the opposite sides of the heat transfer core. ERVs also reduce the amount of humidity, making them a great choice for southern climates. For colder climates, HRV and ERV models also offer core defrost as an option.

Y8150 Fresh Air Ventilation Systems provide an economical way to work with the existing system fan to deliver outside air to the home. Intuitive, 'set it and forget it' programming helps customers avoid adjusting controls, reducing callbacks. With a low total installed cost, it is easy to wire in any orientation, requiring only the included damper, transformer, and control.

UV Treatment Systems Can Help Control Mold And Bacteria Growth

Honeywell Home UV systems installed in forced air heating and cooling systems use proven ultraviolet irradiation in the duct system to reduce airborne or surface microorganism contaminants like viruses, bacteria, and mold. They provide an effective, out-of-sight way to improve indoor air quality. The Honeywell Home UV Air Purifier with AirBRIGHT™ Odor Absorption also reduced airborne odors and toxic chemical vapors inside the duct system.

Typical Installations

UV Air Treatment models are installed on the return duct of the HVAC equipment. The UV100 single lamp unit has moderate efficiency. The UV2400 unit and UV100 Dual lamp unit have high efficiency performance against airborne bacteria in return air applications. The UV Coil Irradiation models are installed in the supply side air duct to illuminate the A-Coil section of the air conditioning equipment. It reduces mold growth and spores on duct surfaces, coils, and drip pans.

Diagram Description: Three diagrams show typical installations of UV treatment systems within HVAC ductwork. One shows a single UV lamp unit on a return duct. Another shows a dual UV lamp unit on a return duct. The third shows a UV coil irradiation system installed in a supply side air duct, illuminating the A-Coil.

How Does UV Technology Work?

Ultraviolet is a high-energy light invisible to the naked eye, which makes up three bands of the light spectrum (UV-A, UV-B, and UV-C). UV-C is the wavelength of light utilized by Honeywell Home UV Treatment Systems to scramble the DNA coding of bacteria and germs, rendering the pathogen nonviable, unable to reproduce, or infect. This is possible because the pathogen's nucleic acid absorbs light energy from 230nm – 290nm, which is within the range of UV-C light.

Diagram Description: A spectrum chart shows different types of electromagnetic radiation, highlighting UV-C light. A separate illustration shows a DNA strand before and after exposure to UV light, labeled "Scrambled DNA."

Key Factors for UV-C Effectiveness

The dosage required is a measurement of light intensity and exposure time, and differs for each type of pathogen. Many additional factors determine the effectiveness of UV-C irradiation:

Lamp Intensity: Higher for airborne pathogens since exposure time is limited.
Lamp Life: Industry standard for effective UV-C emission is 8,000 hours. Resideo uses soft lamps that are chemically coated to minimize mercury buildup on lamp walls, increasing effective operation to 10,000 hours.
Fan Speed: Slower fan speeds increase the time a pathogen is exposed to UV-C. Honeywell Home models were tested at 2,000 cfm in a 12" x 25" duct, representative of real-life applications.
Lamp Position: Three feet of open space both before and after the lamps wherever possible provides the most effective UV-C dosage.
Temperature: Cooler temperatures make it more difficult for UV-C to penetrate the glass lamp wall, which is why UV Air Treatment Systems should be installed on the return duct to avoid exposure to chilled air during air conditioning season.
Maintenance: Dust settling on the outside of lamps reduces the intensity of light, which reduces system efficiency. Quarterly lamp cleaning with a soft damp cloth ensures proper UV-C output.

Served By History: UV treatment solutions are fairly new to the HVAC industry but have been utilized for nearly a century. UV can be installed in new construction, retrofit, and add-on projects. The following pages highlight the types of Honeywell Home UV Treatment systems available and the ideal application for each.

The 24 UV Air Purifier with AirBRIGHT Odor Absorption is installed in the ductwork of your HVAC system to reduce airborne odors, toxic chemical vapors, germs, and mold. The air cleaner's UV light and activated carbon cells reduce volatile organic compounds (VOCs) in the duct system.

Replacement Bulbs literally make replacement a snap, giving you a quick source for recurring revenue.

Achieve Ideal Humidification

Homeowners don't notice humidity levels – unless there's too much or not enough. While air cleaners, ventilation, and UV treatment systems keep indoor air clean, proper humidification is needed to control relative humidity (RH) levels. Too much humidity is uncomfortable and can lead to mold and mildew. Too little humidity can cause dry skin and damage the home's wood furnishings.

Diagram Description: A chart titled "ASHRAE recommended winter design level" shows various factors (Bacteria, Viruses, Fungi, Mites, Respiratory Infections, Allergic Rhinitis and Asthma, Chemical Interactions, Ozone Production) on the Y-axis and humidity percentage on the X-axis (0-100%). An "OPTIMUM ZONE" is highlighted between approximately 40% and 50% humidity.

Typical Installations

Flow-through humidifiers are installed on either the supply plenum or return duct, based on the specific application. Steam humidifiers are mounted directly to the ductwork or remotely to provide humidity on demand. Controlled by a humidistat or IAQ thermostat, whole home humidifiers are designed to introduce moisture directly into the duct's airstream to evenly distribute humidity throughout the home.

Diagram Description: Two diagrams show typical humidifier installations within HVAC ductwork. One shows a "LOWBOY HORIZONTAL DOWN FLO" configuration, and the other shows a "HIGHBOY RETURN" configuration.

Understanding Humidity

Humidifiers operate by the principle that vapor is created when warm dry air is blown over a moist pad (flow-through units), or through steam from evaporated heated water (steam units). As the vapor or steam circulates, the relative humidity rises in the living areas.

Relative Humidity

The amount of moisture present at a given temperature versus the maximum amount of humidity the air is capable of holding at that same temperature. If relative humidity is 35% at a given temperature, the air is 35% saturated with water.

Dew Point

The temperature at which moisture in the air will condense into water droplets. To prevent condensation, dew point must be below the temperature of the coldest surface in the house. If the inside surface of a window drops below dew point, condensation forms.

Infiltration

Cold air holds less moisture than warm air. Without adequate humidification, the natural infiltration of cold, dry, outside air into a home will lower the indoor relative humidity far below the comfort level. During the winter months, indoor relative humidity can drop below 6% as a result. Too little humidity can damage wooden assets in the home, including hardwood floors, staircases, furniture, and musical instruments.

Identifying Whole Home Humidification Opportunities

Homes with lots of wood furnishings, paintings or musical instruments

Proper humidity reduces risk of damage to home's woodwork, flooring, musical instruments, and paintings.

Conversation starters

Did you know many wood flooring companies require a centrally ducted humidifier for the floor warranty to be valid?
Did you know that without proper levels of humidity, wood floors can crack or form gaps and warp?
Did you know your paintings and musical instruments can crack or go out of tune without humidity?

Diagram Description: An illustration shows the humidifying process used by evaporative flow-through humidifiers, depicting water supply, distribution tray, water panel, dry air entering, and humidified air exiting.

Honeywell Home evaporative bypass humidifiers are quiet and highly efficient, delivering the same amount of humidity as competitive models. With advanced models, homeowners also save energy because the automatic damper opens and closes only when humidity is needed rather than constantly cycling air through the bypass. Meet the needs of any home – models are available to supply 12, 17, and 18 gallons per day.

Meet basic needs with a variety of simple controls that can be installed near the humidifier, or in the living space.

Whole Home Dehumidification

Nothing makes homeowners happy like lowering humidity levels on hot, sticky days – especially if you can save them energy at the same time. A Honeywell Home Whole Home Dehumidification System not only improves comfort by lowering the humidity, but it also reduces air conditioning costs because the air conditioner won't have to work as hard.

Dehumidification Works Wonders

Whole home dehumidifiers remove moisture (latent heat) from the air, allowing the air conditioner to focus on removing the heat sensed by the thermostat (sensible heat). This lets the air conditioner operate more efficiently and achieve its designed SEER rating.

Honeywell Home Whole Home Dehumidifiers can also help when lower humidity is desired but cooling isn't needed, such as morning and evenings or during a rainstorm. Because the moisture is removed throughout the home by the dehumidifier, the air conditioner runs less.

Typical Installations

For the ideal installation, the whole-house dehumidifier should draw air from the central part of the home and return it to isolated areas, such as bedrooms, the den, utility rooms, or family room. The unit can draw from the return and dump into the supply if needed, and it can be installed in a variety of locations to meet application needs. The control should be installed where it can accurately sense relative humidity. Honeywell Home Whole Home Dehumidification Systems can also be used as a standalone solution to remove moisture from problem areas.

Diagram Description: Illustrations show typical installation locations for whole-house dehumidifiers within a home's structure: Garage (Ducted), Crawlspace (Ducted, Standalone), Attic (Ducted, Standalone), Closet (Ducted, Standalone), and Basement (Ducted, Standalone).

Ideal Options

Resideo offers a full line-up of whole-house dehumidifiers to meet the needs of any residential application. Sizes are available to cover homes from small condos to large residences. And whether the application requires installing a whole-house unit in a tight utility closet, crawl space, or an unfinished basement, you'll find installation a breeze.

A key feature that homeowners really appreciate: Honeywell Home DR90 and DR120 dehumidifiers are Energy STAR® rated.

How Can Dehumidification Help Control Indoor Air Quality?

ASHRAE industry standards cite ideal indoor relative humidity levels below 51% to deter unwanted conditions and boost overall comfort. Any geographic region with summer dewpoint averages above 55° F are potential growth regions for whole-house dehumidifiers. Whole-house dehumidifiers are designed to provide three key components to better indoor air – fresh air ventilation, particulate filtration, and humidity control.

Diagram Description: A map of the United States shows average summer dew points, with color gradients indicating areas with dew points of 50°, 60°, 65°, and 70°F.

Not Just New Construction

Retrofit dehumidification sales have been on the rise in recent years, making it the HVAC industry's hot-topic comfort solution. Coupling the energy savings message with the ventilation control included with the DR90 and DR120 will help ensure the home is provided with high-capacity, cost-effective dehumidification that will help safeguard the home from excess moisture while improving home comfort.

Signs That A Home Needs Dehumidification

Low set point on thermostat in hot climate
Condensation on walls and windows
Humidity levels above 60%
Uncomfortable sleeping conditions
Portable dehumidifiers

Honeywell Home Whole Home Dehumidifiers

Unlike portable, single-room dehumidifiers that only remove moisture in the rooms where they're located, Honeywell Home Whole Home Dehumidification Systems offer a whole house solution that's more effective and can be less expensive than putting multiple single-room units in a home. Plus, Whole Home models improve comfort and eliminate the need for maintenance (such as emptying collection buckets) – all while using less energy compared to most portable dehumidifiers.

Three models are available – DR65, DR90, and DR120 – so it's easy to find the right-sized unit for any application. Control with a basic dehumidistat or through a control such as Digital Control Humidistat. Honeywell Home Whole Home models also include a MERV 11 air filter to help bring fresh, filtered air into the home.
