Using PETKIT Air Purifying Refills
For PETKIT PuraX and PuraMax automatic cat litter boxes, and K3 air purifier smart spray, follow the specific instructions provided with your device for refilling the air purifying liquid.
Operating Principles
Both the N50 2.0 Odor Eliminator and Air Purifying Refills work by targeting and breaking down smelly molecules, effectively removing odors and keeping the air in your room fresh. The N50 2.0 is designed for continuous release within the litter box waste compartment, while the refills are for devices that spray or diffuse the purifying liquid.
