I have cleaned my HEAPETS P358 Pet Air Purifier, but now the air quality percentage won't go above 0%. Why is this happening?

If your HEAPETS P358 air purifier display is stuck at 0% after cleaning, it usually indicates that the air quality sensor is either obstructed or was affected during the cleaning process. Please try the following steps to resolve the issue:Clean the Air Quality Sensor: The manual specifically recommends cleaning the sensor port and the surrounding area with a cotton swab. Dust or moisture trapped in the sensor can cause inaccurate readings (such as staying at 0% or green even when air quality is poor).Check Filter Installation: Ensure that the filters were reinstalled correctly and that no plastic packaging was accidentally left on them. Also, verify that the filter covers on both sides of the unit are securely closed.Reset the Unit: Try unplugging the device for 30 seconds and then plugging it back in to reset the internal electronics.Check for Sleep Mode: If the display is dim or unresponsive, ensure the device is not in Sleep Mode, which turns off or minimizes indicator lights. Press any button to wake the display.If the PM2.5 reading remains at 0% even when there is visible dust or smoke in the room, the sensor may have been damaged or disconnected. Since your device includes a 12-month warranty and lifetime technical support, you should contact HEAPETS customer service through your retailer's support channel if these steps do not fix the display.

Why is the display on my HEAPETS P358 Pet Air Purifier not turning on, and why is the power cord getting very hot after I cleaned and replaced the filter?

Warning: If your power cord is getting "real hot," please unplug the unit immediately. An overheating cord can indicate a serious electrical fault, a short circuit, or a defective power adapter, which poses a fire hazard.Regarding your HEAPETS P358 display and power issues, please check the following:Sleep Mode: Check if the unit is in Sleep Mode. In this mode, the indicator lights and display turn off. Press any button on the control panel to see if the display wakes up.Power Connection: Ensure the power adapter is securely seated in the power input port on the unit and firmly plugged into the wall outlet. If the cord is hot, the connection might be loose or the adapter may be failing.Filter Installation: Ensure the filter covers are closed securely. While the manual does not explicitly mention a safety interlock, many air purifiers will not power on if the filter doors are not fully engaged.Reset the Unit: If you recently replaced or cleaned the filter, the unit may require a reset. However, a reset usually applies to the filter light, not the main display.Because you reported an overheating cord, this is likely a hardware defect rather than a settings issue. Since the HEAPETS P358 comes with a 12-month warranty and lifetime technical support, you should contact the manufacturer or the retailer immediately for a replacement power adapter or unit to avoid safety risks.

How common is it for the PM2.5 reading on the HEAPETS P358 Pet Air Purifier to remain at 0 when first purchased?

It is common for the PM2.5 reading on the HEAPETS P358 to show a very low number or 0 if the indoor air is exceptionally clean. However, if the reading remains at 0 regardless of the environment, you should check the following:Remove Filter Packaging: Ensure you have opened the filter compartments on both sides and removed the plastic packaging from the filters. The unit cannot accurately sense or clean air if the filters are still wrapped.Sensor Obstruction: The air quality sensor may be blocked or require cleaning. The manual suggests cleaning the sensor port with a cotton swab if the indicator light or readings do not seem to respond to changes in air quality.Test the Sensor: You can test if the sensor is working by briefly introducing a known pollutant (like blowing out a candle or shaking a dusty cloth) near the sensor port. If the number increases and the color-coded indicator changes from green to yellow or red, the sensor is functioning correctly.If the display is completely blank rather than showing the number '0', ensure the device is not in Sleep Mode, which turns off indicator lights. Press any button to wake the display.
