Filtrete 16x20x1 Air Filter, MPR 1500, MERV 12, Healthy Living Ultra-Allergen 3-Month Pleated 1-Inch Air Filters, 6 Filters

This item is not sold in stores due to the size required for a manufactured home. Works perfectly

I was changing the basic filters almost once a week. I decided to step up to these and see if they would last longer. So far the one I put in has lasted over a month. We are seeing less dust in the house, so I would say that these are great filters. Yess they are expensive, so I might not use them all the time, maybe every other change or so.

We have a golden/lab and a ton of pet dander in our home. We did a home remodel last summer and we have a ton of dust. Since we started using these filters I find that they last double the amount of time than the filters I used before (now lasting 2 months) and my husband gets less allergy attacks - big win in our home!

FANTASTIC. I didnt realize how awful the cheap filters were that we were using until we bought this. The old one was literally see through- even with a pile of dirt. This ones thick with several layers to catch the grossness in the air. Photo of filthy old one, vs new.

> Well constructed. Ive had no problems using these for probably 10 years or more. > In my opinion, the MPR 1500 filters are a good compromise, filtering out household dust, pollen, fungus spores, pet hair (i.e., most allergens), and are moderately effective in filtering out bacteria and viruses. > If your main concern is pet hair, then a lower MPR rated filter might be a better choice --- reducing your cost and reducing the frequency you need to change the filters. (Some reviewers claim that they have to change the filters weekly). If you have NO problem with allergens (or perhaps live in desert states), then a moderately lower MPR rated filter might be more cost effective for you. > Higher MPR rated filters (i.e., >1500 MPR) are more costly, and probably provide little improvement in air quality, unless you have someone in your household with a contagious infection; or an individual with a highly compromised immune system --- or other special situations. Higher MPR rated filters may reduce airflow though your AC condenser unit (especially as they clog up more quickly), which may translate into slower cooling, and higher energy consumption. DISADVANTAGES OF LOW MPR RATED FILTERS > Moderately high MPR rated filters (such as 1500 MPR) filters catch most of the material which would otherwise mat-up on the water film of your condenser, reducing its efficiency, which may translate into slower cooling, higher energy consumption, or shorter life of the condenser unit. In hot humid South Florida summers, this is a serious concern -- the dust, etc. that can gets through cheap AC filters mats up on moist condensers, ultimately clogging the condensers, reducing the efficiency of cooling, and therefore increasing your electrical power costs. It cost several hundred dollars to have your condenser cleaned by an AC technician --- which youd probably need to do yearly (at least in South Florida) if you used the cheapest AC filters (say, less than 300 MPR). > Have you seen all the ads for cleaning your airducts, mostly to remove fungal spores? At probably $500 for a typical home? Better that the spores dont get to your ducts in the first place (i.e., if you use moderately-high MPR rated filters). Cleaning might work if you have sheet metal ducting--- But I (and many other people) have ducting built of insulating sheets, which are porous inside --- and I dont believe that significant cleaning (certainly not removing fungal colonies) is even possible. So, I chose what I judge to be the highest practical MPR rate filters (i.e., MPR 1500). BOTTOM LINE I believe that moderately MPR rated filters (e.g., MPR 1500), changed moderately frequently, pay for themselves in short-time electric bills and long term maintenance costs. SCHEDULE > A three month schedule works well for me. After 3 months, the filters are retaining alot of material, but are not clogged. In some seasons, I might be able to stretch to 4 months, but I stay on the 3 month schedule. > I suspect that reasonably frequent changing of the filters pays for itself in lower electrical bills (because the AC doesnt have to work as hard with clean filters). But what is reasonable can vary greatly from household to household, or region to region. I suggest guestimating your schedule, and when you change your filters, inspect them, and adjust your schedule accordingly.

Always loved using this brand, especially with allergies during this time of year.

3M Filtrete 12x30x1, MERV 12 AC Furnace Air Filter, MPR 1500, Healthy Living Ultra Allergen, 6-Pack: I cut these in half to 12x15x1 to fit my Sharp Plasma Cluster FP-P40CX as the replacement for the OEM HEPA filter. I do the same with a Nordic Pure 12x30x1 MERV 8 Pleated Pure Carbon Odor Reduction AC Furnace AIr Filter to replace the OEM carbon filter. The 2 together work fine. Ive noticed no decrease in my Sharps effectiveness. Calcs show that this arrangement saves considerable $ over the increasingly hard to find and super expensive OEM combined carbon/HEPA filter unit.

Do the job

The 12x 20s are getting harder to find. This is a great brand and easy to swap

A little backstory on me. We moved into our new house in 2011. We had a new A/C system so I wanted to get a high quality filter in place immediately. I did my due diligence and selected a Filtrete. Since 2011 we have stuck with these filters and have been happy with the quality, construction and durability. The price is higher than competitors, but my piece of mind offset the additional cost. Recently (Oct 2020), I ordered another quantity of six. Same filter as I have always used. Installed a new filter 24 x 30 . Same inlet opening over the years, however my intake opening is overhead, not in the wall. Took a new filter, and put it in the opening and turned it loose. It promptly fell out on the floor. I have never had this happen before.v Upon checking I find that the filter is actually 23.81 inches by 29.81 inches, but on the label it is designated 24 x 30. I called the manufacturer and complained. It was explained to me that I should have paid attention to the ACTUAL dimensions stated on the label. I have purchased these filters (with the correct sizing on the label for a decade, it is not my fault that they changed the dimensions and said nothing of it on the label. In my humble opinion, this constitutes fraud. They advertise one size, then pull the ole bait and switch with a different filter. I am sure they did it to reduce cost. They have to pay the multi-million dollar quarterly bonuses to their CXX people.. They probably saved $0.01/million filters. Bottom line, I no longer buy Filtrete filters. They had a good customer for the better part of a decade. I would still buy them, if they had remained honest with the advertising information. My suggestion is that you do not purchase these filters because I am quite sure that whatever you buy will be undersized. Shrewd business people. Sell a filter that will not fit the advertised size.
