Filtrete 12x24x1 AC Furnace Air Filter, MERV 12, MPR 1500, CERTIFIED asthma & allergy friendly, 3 Month Pleated 1-Inch Electrostatic Air Cleaning Filter, 2-Pack (Actual Size 11.69x23.69x0.78 in)

> Well constructed. I've had no problems using these for probably 10 years.> I cannot personally attest to the efficacy in reducing allergens, airborne fungal spores, bacteria, viruses, etc., because I've been using the filters so long, that I don't know if I'd notice a difference without them. But I presume that they are helpful. Frequently, the minute I set foot outside, I have an allergy attack.> CON the filters reduce airflow though your AC condenser unit, which may translate into slower cooling, higher energy consumption, or shorter life of the condenser.> PRO the filters catch most of the material which would otherwise catch on the condenser, reducing its efficiency, which may translate into slower cooling, higher energy consumption, or shorter life of the condenser unit.> TRADEOFFS -- Bottom line, I don't know whether the filters improve or degrade the efficiency (life, etc.) of your AC unit. But I do believe that the filters improve the air quality in my home.> Changing every 3 months is a good schedule for us --- the used filters have plenty of "crap" in them, but are not completely clogged. If you live in a particularly dusty area (such as the southwest) or have cats or dogs, I suggest changing the filters every month or so.

I need to replace filters every month so I purchase these often. Prices have been raised quite a bit for air filters & I’ve tried so many. These work perfectly & are a better price than other thicker ones I’ve tried. Fit is a little off, too large by maybe 1/8-1/4 inch for my space but can be pushed in & adjusted without any gaps. Works for me, especially because we change them every month.

I would highly recommend this item. I use them in small classes that I have, and they are well liked by my students.

It’s a filter. It filters.

I find the 1500 series of these filters to be the sweet spot for filtering out the air in our home these last us about a month and I change them out regularly. It only takes a side by side comparison between the one I took out and the one I put in to see just how much junk was in the air that these filters cleaned out before it got to us that is a priceless value to me and my family thank you

Great Filters for pet onwers

I have ordered the same product twice and it's easy to install and my daughter have bad allergies, so these are great to have.

Fantastic filter has lasted way longer than others also very sturdy and true to size

Can't recommend the product the pressure drop was so big .45 in my case that it would cause the limit switch in the furnace to trigger meaning the burners would go off but the fan would stay on (safety feature) blowing cold air. Used a cheaper filter Merv 8 and the pressure drop was only .25 and no issues with the switch being triggered, if you're getting these high end filters make sure your furnace can handle the pressure drop increase also these filters just makes your furnace work harder (more energy) to circulate air.

I have purchased the filters to remove smoke particles and odor from forest fire smoke blown into our area. The filters work as expected and remove smoke in the house. I was very satisfied with their performance. Fortunately, the smoke was blown into our area only for a period of a few days, so my filter test has been rather short.

These are just about the highest quality furnace filters on the market, and the price is better than ANY STORE. Walmart, or CanTire included. Awesome things. Spending extra money for high quality filters saves your health, and you will notice that dusting almost becomes unnecessary. They're that good!

its a happy medium between small particles getting captured and using a even higher MPR that basically blocks your air flow completely and makes your furnace work way harder to push air through. for people with allergies like myself it works amazing, our ducts stay cleaner as a result and as long as you change it regularly you will get all the benefits of it.

but expensive:(
