Filtrete 12x12x1 Air Filter, MPR 1500, MERV 12, Healthy Living Ultra-Allergen 3-Month Pleated 1-Inch Air Filters, 4 Filters

Does a fantastic job keeping our air clean with my wife and kids having allergies

These filters arrived super fast love Amazon Prime. I have used their products for years and I am on oxygen so I have to have the air super clean and these are perfect. This is one area of my home maintenance I will not compromise. Even before I had to be on oxygen I only used these because they honestly keep odors down and its NEVER musty smelling in my home. I once had a brand new home and I used crappy filters at first and learned to never skimp on air filters. You will pay a little more, but it is totally worth it.

Original quality, no issues

Shipping box and filter came damaged in 1 corner.

> 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.

Have used 3M furnace filters 1500 for years. They filter very well. Change them every 2 months or sooner if necessary. Ordered their 2200. Haven’t used them yet, but filtering reports seem good.

Item is just a little to big to fit in the opening, had to crush the sides to be able to install in my 14x14x1 air return.

A Little pricey. They work. Nothing exciting about these

Exactly what I ordered

I Have A Central Unit That Uses Electric For Air & Natural Gas For Heating. I Also Have Pets As Well. Therefore; Installing A Good Quality Filter Is Mandatory. I Recommend This Filter.
