Product Details

Nichols Heating and Cooling-Tackle up to 99% of pollen, mold, spores, dust and other airborne allergens inside your home with the Aprilaire 401, 2400 replacement whole house air filter media. How is that possible? Patented SelfSeal technology combines with the electrostatically charged MERV 10 rated filter media to cut air gaps for more effective particle capture rate and less pressure drops. To say it simply, air coming out the other side of the filter is cleaner and it stays that way much longer. Clean air means better breathing. For those with allergies or other respiratory illnesses this should come as a relief. We spend much of our time indoors so keeping the air we breathe pollution free is big step to healthier lungs and body.

    I upgraded my Aprilaire system to the newer Spacegard 2400/Aprilaire 240. The retrofit was easy to install and the filters are easier to replace than the old Aprilaire system. The filters are superior. Glad I found Nichols Heating and Cooling, they had what I needed!
