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

Looks like a 5 year old child wrapped the filters . The end of the fillers , witch are cardboard , were exposed to the elements and bent . Good filters bad packaging .

I have always loved these filters. But for some reason they do not make a 19.5×19.6.. I have to master cut two sides of the 20×20 to make them fit my intake. I do NOT recommend doing this, but since I have master had skills, I choose to do it because I do not like the cheaper size that does fit. I also noticed they no longer include the paper insert, they want to save money on the paper but do not pass on the savings to us. Yes, I need to change my filter now, time to cut and tape another one lol..

As a filter, it’s fine. But it won’t pair with my IPhone so all the tech I bought it for is useless. Tried for over 2 hours and both my wifi networks. (5 and 2.5). So if it won’t pair, it’s just a normal filter. Kicking myself for this huge waste of money and time. Update: it says it can’t connect with “local monitoring station.” I did a quick to find out what that is and it isn’t listed anywhere for Filtrete.

This product is about aa 1/4 inch to long and wide. Can still press in.

We have two German Shepherds and one blue tick beagle/hound. Daily chores include vacuuming (requires dumping bin twice full of dog hair, 1/4 cup of dust in bottom). We have to change ours WEEKLY. If you dont want your house smelling like the pound (your nose adjusts if your homeowner, guests notice), or sensitive sinuses/allergies like myself- youll want these filters. They capture so much from the air. The DRAWBACK is the price. And if you have dogs like I do, these filters get black QUICK. We have to change ours every 5-7 days during the summer/winter months when unit is flowing air the most. We also have a air purifier in the room that helps. I hate the price but Ive tried lesser quality or less rated and it just doesnt do the job. So we just have to pay up as cost of owning dogs!

I recently moved from a house to an apartment. I always used these filters at my house and continued in the apartment, instead of the cheap ones that are typically provided for tenants without charge. Goodness, I dont remember my filters being this dirty so quickly in my house! This apartment obviously is much smaller in square footage, although I do have two Persian cats. Between my Honeywell air filters, these 3M Filtrete filters, and my Rainbow vacuum cleaner - it really does control the dust/dander in my small space. Lastly, I should mention that I also have asthma. I trust this product and will continue to use it.

They are a little oversized for the opening in my place, but I like a tight fit for filtering air. I change them every three months. If we have a fire in the area, I can sure tell it by the filter.

Keeps the dust down and they are easy to install.

3M produces the best air filters in my opinion. I’ll keep buying.

> 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.
