Put the model 16x25x4 in Bryant furnace, after one run the cardboard retaining material was sucked in and had to destroy it to get it out. As a 3M stockholder I am not happy\.

My family has allergies to include to dust mites, etc. Using this filter has had a noticable difference in their health/feeling around the house. Thrilled that I got them and they keep the air nice and clean!

Remember these filters are for Standard size Returns. However there are HVAC companies that deliberately use Grille size Returns to make a customer buy their filters. GRILLE SIZE Returns are slightly smaller than the Standard counterparts.

This filtering system is wonderful for our basement. We have two plant tables in the winter that are over 6' long, and the Filtrete really clears the air!

I know this filter works because when I change it, within the 90 day recommended time, with its fine filter capabilities, it really does its job as the filter is grey with particles.

Am very satisfied with the effectiveness of the Filtrete 16x25x4 filter. I have a variable speed fan on my HVAC unit, and run it 24 hrs. 365 days. My house stays fairly dust-free. I am happy to let the filter do the work for me!

I don't have many brand options for this product because of it's configuration. Fortunately, Filtrete makes one and I've had great success for years with Filtrete air filters.

I usually have used these in the past and recently purchased a different brand. I prefer these. They are better constructed and appear to better clear the air.

We use a gas fireplace as a supplement to our heat pump during the winter months and we have a cat. The filter keeps the coils on the indoor unit cleaner than another filter we have used in the past.

As a long time Filtrete user, I remain impressed at its ability to do exactly what it's supposed to do. I have less dust, less odor, and just generally cleaner smelling air. It is worth the price.
