When I buy these, I look for the lowest cost including shipping. Quality is determined my the manufacturer. My furnace actually tells me when to change the filter and it's usually 2x/year. It does not use time, but rather static pressure. The furnace does a daily test with all vents open for about 10 min each day. I've put mini-labels on the filter box itself to remind me which side the box goes. it's actually mounted like [...........] on the ceiling. Airflow down. And a reminder that you have to open the ends. A full filter history is written on the filter housing using post-it tape. In order to substantially reduce installation time, I purchased a comb which I cut on an angle and rounded the ends. It also is identified with paint. Once you get that comb in the pleats, you can insert the others so that they are bunched together. Now spread and clip into their respective places. Total time is about 15-20 minutes which usually includes cleaning the wires and hosing the larger grid.Read full review

This filter helps to keep the inside air quality better along with plants and infra-red air cleaner light. The filter is very thick and made of high quality materials.

I have had a aprilaire unit 5+ yrs. These filters are the only ones that will fit it. The filter comes packaged nicely. It is easy to install. It is amazing at what it all filters. Well worth the money for a filtered home.

I have had my Aprilaire 5000 for nearly 8 years now. I change the filter media once a year & always get the original replacement parts. This set of three filters is all original. I have yet to replace the filter media this year but am sure it will work fine.
