Engineered to meet the challenging needs of allergic and asthmatic individuals, AllerTech® Furnace and Air Conditioner Filters ‐ 4-Pack, are hands down the best furnace filters available for anyone with allergies or those wanting an affordable, high-performing filter. There are always trade-offs when it comes to choosing which furnace filter, but not with AllerTech® filters. AllerTech® Furnace and Air Conditioner Filters use the most efficient means to trap and hold allergens, offering far superior performance over electrostatic, pleated or fiberglass filters. While competitive filter performance degrades over time (and often times with a much shorter service life than advertised), AllerTech's filtration performance actually improves over the filter's longer 3-month service life, and with lower replacement costs when it's time to change the filter.

AllerTech furnace filters provide three progressive layers of filtration, efficiently capturing particles both large and small. AllerTech furnace filters are frameless, which really sets them apart from the pack. Most furnace filters are framed – either in metal or cardboard. Unfortunately, framing allows some particles to bypass the filter, where they escape to leak back into the air you breathe. In contrast, AllerTech frameless filters feature a No-Leak Edge, creating a self-seal so that 100% of incoming air passes through the filter with no particle leakage. Based on the design of the filter media itself, AllerTech's self-seal design has no negative impact on air flow through the system. MERV 10 rated. Lasts for up to 3 months.  Package contains four (4) AllerTech® Furnace and Air Conditioner Filters – a one-year supply!

It's still early, but these allergy-reducing furnace filters seem to be working much better than our store bought ones. Service man who cleaned our air ducts suggested tighter fitting filters. These filters are more expensive, but well worth it compared to cheaper ones available at big box or hardware stores.
