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

I have horrible allergies. This filter really makes a difference.

Great product and fast delivery.

> 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.

Works as stated.

Great value and noticed the difference in dust level immediately

Seems to be really good quality, not a cheap flimsy one. A bit too wide and had to really work to get it squeezed in. Length seemed fine. Best filter I’ve bought.

For years I have been buying a basic Filtrete filter, costs about $40 for 6 and I replace them every month. I tried this higher quality filter with Bluetooth to get more life from the filter and visibility into remaining filter life. I am one month into the filter, it’s down to 50% remaining life, but my furnace is shutting down. The HVAC people confirmed that it’s because the heat exchanger is overheating due to lack of airflow. Even though the Bluetooth on this filter is saying there is 50% life remaining, it’s completely full and probably should have been replaced a week ago. In comparison, the cheaper filters that I use will last as much as 5-6 weeks if I run out or forget to replace them. I’ve never had my furnace shutdown due to overheating. We have a clean house and vacuum regularly. No pets that would prematurely clog a filter with dust. I do not recommend this filter as it’s lifespan is overstated, and the Bluetooth monitor is not accurate.

Filtration is the best filters for my family and I. It helps in keeping allergies, dust, viruses, pet dander, bacteria from my family and I. We breathe much better by keeping the filters in as needed.

I was using a MERV8 filter from a hardware store brand. It was fine for the first few weeks, then i started having breathing problems - i.e. was having a hard time taking deep breaths once in a while in the house. I felt like my lungs were straining when i was trying to take those deep breaths. My house has some rugs and a big dog, but mostly hardwood floors, and havent had these issues inside the house before. Resuming my allergy spray did not help. So I bought this filter from the hardware store last night and replaced the MERV8 one (it was barely 3 days old and almost new) - within about an hour, i was back to normal! No more breathing issues inside the house. If you are sensitive and prone to allergies. then this is a must buy - its not optional.

A good filter. You can spend a fortune if you want to filter out everything. This seems to be a decent range filter for a decent price. I buy the two pack and change them every ninety days. It will extend the life of the unit.
