Filtrete 12x12x1 AC Furnace Air Filter, MERV 13, MPR 1900, Premium Allergen, Bacteria & Virus Filter, 3-Month Pleated 1-Inch Electrostatic Air Cleaning Filter, 2-Pack (Actual Size 11.81x11.81x0.78 in)

These are my go to ac filters. They are thick enough to filter out dust but not too thick to put a strain on your ac system. They are always filthy when we change them as compared to others I’ve purchased so I know they are doing their job. I now change them every two months instead of 3. They fit my 20x20 space perfectly and I find the price reasonable for the quality.

Filters are Actually the Correct Size ! Spendy but do the Job! Tight Fit to Filter the Air Completely

I put it in this morning, and Iʻm noticing the difference already. My area flooded, so there was a lot of water in some parts of my house for days. Mold was — is! — growing, and the cleanup and teardown of some walls and carpets is putting a lot of allergens in the air. The filter fits perfectly, does what it is supposed to do, and is the right thickness or depth not to put a strain on my air conditioning. It keeps the air clean, catching everything from dust and pollen to smaller particles. The air feels fresher, and it’s reassuring to know it’s removing allergens so effectively without slowing down airflow. My eyes tear up when the lawn gets mowed, and I have trouble breathing when I play with my dog, so I am keenly away of the improved air quality since installing this filter. My congestion is less, my eyes are not puffy, and I am not sneezing or coughing or itching anymore. Although these have a premium price, they are premium quality, so you get what you pay for. Maybe more. i donʻt think this is rated for odor reduction, but the musty smell has definitely decreased over the course of the day.

the perfect filter for old furnaces; according to testing this model provides least air resistance, and does the job of trapping pollen and mold mites.

While I do love these filters, the tiny issue I have with them is that the filters aren't individually wrapped. I can tape shut the plastic they come in but yeah. Overall the size, thickness, sturdiness, & dust collection of the filter is great.

I felt they were a good price . I priced them in other stores, 1/23/26

The 1900 filter was highly rated by Consumer Reports a year or two ago. Large filter surface area but good air flow. Replace one every 3 months.

great product

I use these as a cheap emergency replacement for HEPA filters: when stacked in series two of these 1" filters reduce the 0.3 micron particles 50-fold (98% arrest, verified with a calibrated particle counter). The 12" size is relatively standard , and fits into standard housings. These Filtretes are odour-free, unlike costly HEPA filters from certain supplies (e.g. IQAir). Now, I wish they costed less (hence 4 stars).

good hvac air filter

Excellent product. Very little dust in the house now. Merv 14 extra reassuring specially with this covid-19 growing around. Makes for a feeling of fresh air in the house.
