Less dust
Noticeably less dusting needed when using this filter. Also keeps our furnace very clean - said our HVAC serviceman.

16x20x4 does not fit Honeywell / Lennox filter box
Buyers beware: The actual size of the 16x20x4 was reduced at some point last couple of years. As the result it doesn't properly fit in Honeywell / Lennox filter boxes, despite the advertisement on the packaging. The filter size used to be 15-7/8" x 19-7/8" x 4-5/16". The new filter size is 15-7/16" x 19-3/4" x 4-5/16", so it is 7/16" (1 cm) narrower than the old filter.

How About a 18x20x1 filter rated 1900?
I need a 18x20x1 1900 filter but Filtrete doesn't make one, settled for a 1500 but not satisfied. Found an Aerostar filter and an evaluating it, but would prefer Filterate for good quality control and honest rating assessment.

Best Filter for Us
This is the only product I purchase for our furnace. I particularly like that it only requires changing once a year. When we changed ours for 2024 we discovered that it could have remained in place longer.

Best Filters
This is the only air filter we purchase for our current home. Our old home required the thinner filters, but all are always Filtrete.

Undersized. Not of advertised value.
Product size states 20x25x4. Inconspicuously designated as slim fit. Actual size is 19.5x24.5x3.25. This is new. I have purchased this product for many years. This is the first time I have encountered this.

Extremely beneficial for my allergies
Upon advice from my doctor to purchase a better a/c filter, I researched and purchased two of these. We quickly noticed a difference in the air quality, my headaches and sneezing are much better now. I am allergic to dust mites and my cats dander - I am extremely impressed. When I clean, there is far less dust accumulated on surfaces in my house which is lovely. After changing the filter recently we found out why - this filter is blocking everything. So great! We are considering investing in higher grades of the Filtrete brand because this one has done so well.

Excellant Filter
I upgraded from the Allergant Protector (also a great filter) just to see if I could tell a difference. I can! The air seems cleaner and it gives me peace of mind knowing that it helps with bateria and viruses.

4 in filter too wide
I purchased this based on the recommendation of my HVAC installer. The filter is TOO WIDE to fit in the AC. The 4 in filter is wider than the "same size" 1 in filter. Are there any narrower options as opposed to slim options i.e thinner.

You Deserve Clean Air
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.

Clean smell
Purchased this after some work on air conditioner. I will continue to purchase these filters as opposed to the cheap ones. Improvements in odor, dust.

Great Filter......and once a year!
After my electronic air filter system failed, I decided to to try the Filtrete Air Filter. (1550, 4"). I have been using it for the last four years. It seems to work every bit as as well as the expensive electronic system. I thought we would notice more dust in the house, but that is not the case!!

clean air for asthma sufferers
I use these in place of regular HVAC filters. The 4" depth adds surface are which reduces air flow resistance. My home systems for people with breathing problems includes multiple 20 x 20 x 4 inch filters. My 2400 sq ft home has 5 filters. The efficiency of the HVAC system is not degraded yet the air is best for sufferers of breathing problems such as asthma, RADS, or allergies.
