Good filter. Although it is advertised as lasting up to 12 months, I feel the need to replace it every 2-3 months. I have a VERY difficult time removing it from air cleaner, as there are no holes in the filter in which to insert your fingers to grab it for removal. A simple design change would make it more user-friendly. I've found that I have to use a knife to cut a hole in the filter cardboard to have something to hold on to. Also, the cardboard strips on the sides usually get caught in my air cleaner, so as I'm removing the filter, I really have to pull hard, tearing the side strips, as I remove the filter.

Filter says 16x25x4 but it is actually 4.25 thick! Does not fit in my furnace which is exactly 4.0" This is an extremely frustrating problem and every store carries the new 4.25 filter and apparently nobody makes or carries the old 3.75's anymore. I could cram a 4" in there but not one thats 4.25. Trust me, I tried.

I live in Michigan and my 2 furnaces run constantly. It is extremely important to me that my family breathes clean, dust/allergen free air. Plus, it makes house cleaning so much easier. The filters are high quality, easy to use and I only have to change them once a year. I wouldn't buy any other brand. Filtrete whole house filters work!

The way our air system is set up, we have a 1200 filter installed just under our unit, but we also have another filter mounted in the door. The air is sucked in through the door filter first and then up through the one in the unit. We LOVE this set up and we LOVE using Filtrete filters. With my husband's asthma and allergies I don't know what we would do without them! Thank you Filtrete!

[This review was collected as part of a promotion.] I love everything about this filter. It does an amazing job, it's easy to install, it comes in the hard-to-find size that I need, and the optional email reminders that it's time to change the filter make life easy and healthy.

We purchased this filter for the first last year. It is an amazing filter. Product does a great job filtering out dust in our home. You can actually see the difference in the minimal amount of dust in the house. It's a great product. Would recommend to any body needing a filter.

After changing my regular pleated air filters with these, I essentially was able to come off of allergy medicine daily. I used to get allergy shots. Now I very rarely get an allergy flare up. I highly recommend allergy sufferers get this filter. I hesitated beforehand too but thought what do I have to lose.

Upon advice from my doctor to purchase a better a/c filter, I researched and purchased two of these. We quickly noticed a difference in the air quality, my headaches and sneezing are much better now. I am allergic to dust mites and my cats dander - I am extremely impressed. When I clean, there is far less dust accumulated on surfaces in my house which is lovely. After changing the filter recently we found out why - this filter is blocking everything. So great! We are considering investing in higher grades of the Filtrete brand because this one has done so well.

I used to use those half-inch wide throw-away $2 fiberglass filters on my old furnace. But when I invested in a high efficiency furnace, I decided to go with better air quality in the house, too. Boy did I get it. My Filtrete 4-inch wide furnace filter traps a lot of stuff I don't want in the furnace, no less the air I breathe. I have a dog, and though I keep her groomed, there is still dog hair left over; the filter is doing a great job filtering out dog hair that would otherwise enter the furnace air supply. It's a comfort knowing my home is a little cleaner and the air is a lot more breathable with a high quality Filtrete filter.

[This review was collected as part of a promotion.] This is absolutely the best air filter I have found for my home. We had some minor construction in our kitchen, Sheetrock, taping and sanding. Dust was everywhere. Installed one of these Filtrete Healthy living filters and the air quality improved within minutes. I change my filter every season, the Healthy Living filters trap so much dust, dander and who knows what else. Great product worth the price!
