Filtrete 25x25x1 AC Furnace Air Filter, MERV 12, MPR 1500, CERTIFIED asthma & allergy friendly, 3 Month Pleated 1-Inch Electrostatic Air Cleaning Filter, 6-Pack (Actual Size 24.81x24.81x0.78 in)

Origionally I bought these because i made a $50 bet with my husband that a quality air filter can help alleviate allergy symptoms in the home. He swore the only difference in air filters was the price. I don't know what I enjoyed more, the $50 or the moment I looked him dead in the eye & said those glorious words "I told you so"

I bought these filters to try what many consider the 'gold standard' of HVAC filters. What a joke. The first two images show gobs of hot melt glue on the paper face of each of the filters. This is the face that should seal up to the air return filter housing. No sealing taking place here. While this is just poor quality control. The more egregious fail is in the economy approach to overlapping the cardboard frame in each of the four corners. This is a designed in leak path that they deliberately build into each filter, in each of the four corners. Every filter, every corner, every day. Trivial, you say? They promote filtration down to 0.3 micron in this model, yet put four leak paths of .017" (254 microns) in each and every corner? Sorry, this approach is just bogus. These two filters are going in the trash, and I'm back to the Nordic Pure MERV 12 product. Better design, better QC, 1/3 the cost, and made in the USA (vs. Mexico for 3M).

I have been using subscribe and save for my filters lately, but I have been having problem with them coming damage. This particular time the, box was undamaged but the filter has a damage circle of it. I will have to go back to buying them locally.Here is my review of these filter. I have used many different strengths, but downgraded a little because of the cost.SHORT ANSWER: These filters are great and I can tell a difference when I used a higher grade filter but that can vary depending on the level that I started and how clean the house was previously by a high filter. Don’t forget to check the air filter regularly because a dirty filter can cause the coils to freeze up and will need to be turn off to unfreeze. Don’t forget to have your AC/heater check and make sure you tell them to clear the line (they may not normally do it, but should.)LONG REVIEW:I started using 1500 (at the time the purple label) and have used up to 2800. I live in a place where I get very sick because of all the pollution, pollen, dust, and in the winter smoke from miscellaneous burned things from across the border.How well do these work …..well that depends on how you live your life.We for the most part keep our windows and doors closed and always run the fan on a/c (heater) unit so it is alway cleaning the air which was recommended to us. If you have pets and open your window and door a lot and keep them open it will be hard to keep your air cleaner. The cleaner you have your house the better it will be vacuuming, dusting, etc….We have box fan with 20 x 20 filters on it. We tried using, them then we stop, and now we are using them again. We started using 1500 and upgraded recently to 1900.At first I thought when we used the 2800 filter it was really only a physiologically made me feel better, but I up graded our fan filters from 1500 to 1900 and notice they appeared to get dirty fast. After that observation I believe they make a difference.How fast can it clean your air? Depend on your life (mentioned above) and house size. I have notices that it can take about month or so to clean our small house.There is a visual difference the higher you go. The higher filter look different with more pleats and a stronger gauge on the wire across the front and back.KEEP IN MIND**If you don’t change your filter when it gets dirty it can freeze the coils because of poor air circulation and you will need to leave the air conditioner off for a while to melt the coils.**Regular maintenance can prevent problems make sure you have your ac/furnace is check year and TELL THEM TO CLEAR THE LINE (they don’t always do this automatically) and can get clogged and cause flooding.**AC not turning on also check the batteries.I’m sure there are more, but these either happened to me personally or I heard about them and wanted to pass this knowledge along.

Has made a positive difference, for everyone in our home. The other day, after our day was ending, we both had noticed how nice it was 2B able 2 enjoy our dinners w/o the sounds of runny noses, 👃👃👃being sucked up. Or 🌬 blown out in2 tissues, cloth napkins, or the closest piece of clothing that, that some1can find. In order 2 prevent them frm spraying a sneeze, all over the table, the foods & drinks or even the worst, others sitting next 2 the person doing the sneeze 🤧. Unfortunately, I 4got 2 take a B4 & after photos 📸 of the filter. However, I believe that it is extremely important 2 do so. It will B very helpful 4U 2 see 👀 how much of the stuff that is in the air, is actually filtered out. The reason I feel like this is important, is bcuz I have yet 2B able 2 leave the filter in 4 the recommended efficiency time. The filter is so effective the efficiency of the filter. Although, the recommended length of change every 3 months. After about 5 - 7 weeks, I have had 2 replace the filter in order 2 maintain the efficiency in cleaning the air. We live in a very clean area, that has well maintained grounds w/ groomed hedges trimmed trees & no non maintained areas around us. A clean neighborhood

I've been buying the Filtrete MPR 1500 Ultra Allergen filters for years. I will likely never go to another type of Filtrete, not to mention a different brand. If anything, I may go up a level or two if I ever anticipate lengthy construction projects in my home. However, I can say without a doubt that I feel my 3200 sq ft home has noticeably cleaner air. I've even had a slip of the mind and didn't change the filters for over four months before. Keep in mind, that's NOT a good idea.Nonetheless, the filters kept working fine and I noticed no degradation to my HVAC and during regular maintenance, there were no issues in my home system. Again, I strongly advise replacing them every three-ish months or less. I'd say that during normal operation, one should inspect the filters at least once a month.These filters are not restrictive whatsoever. I haven't noticed any issues in my heating and cooling for as long as I've used them--including when I accidentally went over in their lifespan.I'll keep buying these for as long as they make them and quality is maintained! Unlike some other reviewers, I have never had an issue with quality. I'd also like to point out that I do not care if the cardboard around the filters has tiny imperfections. It's hidden and has never affected the air quality or function of my system whatsoever.Buy these! You won't regret it.

Can't recommend the product the pressure drop was so big .45 in my case that it would cause the limit switch in the furnace to trigger meaning the burners would go off but the fan would stay on (safety feature) blowing cold air. Used a cheaper filter Merv 8 and the pressure drop was only .25 and no issues with the switch being triggered, if you're getting these high end filters make sure your furnace can handle the pressure drop increase also these filters just makes your furnace work harder (more energy) to circulate air.

These are just about the highest quality furnace filters on the market, and the price is better than ANY STORE. Walmart, or CanTire included. Awesome things. Spending extra money for high quality filters saves your health, and you will notice that dusting almost becomes unnecessary. They're that good!

its a happy medium between small particles getting captured and using a even higher MPR that basically blocks your air flow completely and makes your furnace work way harder to push air through. for people with allergies like myself it works amazing, our ducts stay cleaner as a result and as long as you change it regularly you will get all the benefits of it.

I have purchased the filters to remove smoke particles and odor from forest fire smoke blown into our area. The filters work as expected and remove smoke in the house. I was very satisfied with their performance. Fortunately, the smoke was blown into our area only for a period of a few days, so my filter test has been rather short.

I was a little worry about the shipping damage when I ordered furnace filters online.They came well packed in factory box of two filters. Perfect for my furnace and good price.
