Product Description
Designed by expert engineers to meet the needs of allergic and asthmatic individuals, AllerTech Furnace and Air Conditioner Filters use the most efficient methods to trap and hold allergens. Our exclusive disposable filters are superior to both electrostatic and pleated filters.
Our Three-Stage Design filters become even more efficient over time, capturing smaller and smaller particles. Other types of filters lose their efficiency as they get dirty and unload particles that they have collected back into the air.
Our No-Leak Edges create a self-seal that directs the air through the filter for 100% filtration. Other types of filters have cardboard or hard metal edges that allow dirty air to pass by unfiltered.
AllerTech Furnace and Air Conditioner Filters are easy to install and require no maintenance or messy cleaning. Sold in boxes of four for a minimum 12-month supply.
If you have a Lennox furnace, please use our Basket Guard filter and simply cut to size and place in basket.

I really like these...,

Amazon Verified Purchase(What's this?)
This review is from: AllerTech® Filters 20" X 25" X 1" (4) (Health and Beauty)
I know they're expensive but I just feel like the air feels cleaner... might be psychological ;)What I try to do is at the beginning and end of a season, if we haven't used the heat/AC much, is use a crappy 4$ filter to absorb all the dust and detritus accumulated in the system.... maybe do that for a week of cycling.... THEN I put one of these puppies in for the long haul.... that way I feel I can leave these AllerTech's in for twice or thrice as long (6+ months?) I guess if you run your system frequently or are diligent about rotating your filters, then your mileage will vary. I like this material and I like the airflow. I don't know much about the science behind it but I'll continue to buy these until I decide to cheap out again. Maybe the ideal is to rotate between these and the cheapos depending on the season. I say give it a splurge and see what you think!
