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\.

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.

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.

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!

Been using these for 6 years. They do the job but the 6 pack price has increase 60% in that time. If that rate of increase continues think I'll start looking for an alternative.

We have used Filtrete for years and it works fantastic. Because it works so well, we find ourselves changing the filter more often than the package says. It is amazing how much it collects and keeps out of our air.

[This review was collected as part of a promotion.] My husband bought another brand last time and is there ever a difference in performance. Not even close. Back to Filtrete Purple!

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.

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.

According to our service technician, pet hair can wreck havoc on your HVAC system. The Healthy Living Air Filter addresses the issue so that it is no longer a problem. Works great!
