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"'}, {'review_meta': 'Reviewed in the United States on May 13, 2022', 'review_star': 'a-icon a-icon-star a-star-5 review-rating', 'review_body': "OK, here's the deal. Brand new modular house in the Midwest (northern Michigan), delivered in January. Bought A/C - it was optional - just in case wife's allergies would flare up.\n\nToday they did. She took a Claritin and it helped some, but then after an outing, returning home, she started sneezing about every 4 seconds. She was miserable! So was I.\n\nThrew a new one of these into the HVAC system, turned on the A/C, her symptoms subsided in minutes. I mean literally in about 4 minutes.\n\nIf you love someone with allergies, you will know how terrible it is when you can't do anything to help them.\n\nI wish these filters had been available when my son used to suffer from seasonal allergy.\n\nThis is not a luxury purchase.\n\nNow, I have not done a side-by-side comparison test, though I do have some less expensive filters sitting there just in case - or maybe I'll throw those in, in the winter months (which is about 7 months per year here). So, other filters might be just as good. I don't know and I don't care - I'm gonna keep buying these because I love my wife and want her healthy and happy, not miserable."}, {'review_meta': 'Reviewed in the United States on January 12, 2020', 'review_star': 'a-icon a-icon-star a-star-5 review-rating', 'review_body': "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.\n\nNonetheless, 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.\n\nThese 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.\n\nI'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.\n\nBuy these! You won't regret it."}, {'review_meta': 'Reviewed in the United States on January 13, 2019', 'review_star': 'a-icon a-icon-star a-star-5 review-rating', 'review_body': "These filters are great, and exactly what I wanted. One HUGE NOTE OF CAUTION is how and when you place your order. I recommend that you purchase them by themselves and not even within days of when you place any separate orders containing anything remotely heavy or sharp. Amazon will ship these combined with anything without regard for how fragile they are, and they'll come crushed or torn if you're not careful. I've had to return them which was a giant PITA because my nearest UPS store is 45 minutes away. Other than that, they've always been what I ordered, without any fakes."}, {'review_meta': 'Reviewed in the United States on January 6, 2020', 'review_star': 'a-icon a-icon-star a-star-5 review-rating', 'review_body': "I have tired many air filters over the years and have come across 2 problems. One, the filters that protect better, often restrict the air flow too much and have actually shut down my furnace. Two, the air filters that allow good air flow don't filter very well. This is the best air filter that I have found that will both filter well and also not restrict air flow. If you have any of the two issues I did, do not hesitate to give these a try."}, {'review_meta': 'Reviewed in the United States on June 19, 2018', 'review_star': 'a-icon a-icon-star a-star-5 review-rating', 'review_body': '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.

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.

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).'}, {'review_meta': 'Reviewed in the United States on July 13, 2021', 'review_star': 'a-icon a-icon-star a-star-5 review-rating', 'review_body': "I used to buy various MPR ratings of these Filtrete filters for our 25 year+ old A/C and heater unit until I determined these MPR 1500 seemed to be the right price/MPR cleaning rating for our needs here in Arizona. I had been worried that a higher MPR might put an undue stress on our A/C fan, so I settled on these 1500 MPR ones and didn't really notice a difference in how dirty the filter ended up after using it for 400 hours (about 3 to 4 months of operation). In the past I've used cheaper brands, as well as reusable ones, and I feel very satisfied that these are cleaning the air in our home at an optimal level for preventing dust and reducing allergens. They are very well built and could easily go more than 400 or 500 hours of use, but I think swapping them out every 400 hours, as I do, is the right thing to do for our health. They also cost the same as buying them at a big box store, and you can always be assured of buying the same exact ones by reordering when needed through Amazon."}, {'review_meta': 'Reviewed in the United States on October 8, 2019', 'review_star': 'a-icon a-icon-star a-star-5 review-rating', 'review_body': "I have used this brand and style of filters for quite some time in a previous home. I am glad to find them for quality, price and subscription on Amazon (I can remember to change the filters when they show up!). The frames are sturdy as are the pleats in the filter. My A/C has a strong pull in the return air vents (2 in the ceiling of the hall in my home). The previous owner's filters practically got sucked into the return air and the pleats were weak so they became deformed easily. The frames in these filters not only hold firm against the draw of the return air, but help me get them into the vent frame without wobbling on the way up and into the vent frame. The fit is firm and snug as well within the vent frames. I have to use the 6' ladder and reach above my head -- so the strength of the frame is extra necessary for me to install them. I've been peeking at them through the vents with a flashlight and can tell they are handling the lint and so forth much better than the previous filters. I have 2 dogs who come and go often inside and out. One sheds if she blinks. It's important to me that their dander, dust and so forth are caught by the filters and not go into the A/C unit. This is one reason I've used them for a number of years, it's just the first time I've had to install filters into the ceiling for an A/C."}, {'review_meta': 'Reviewed in the United States on March 29, 2022', 'review_star': 'a-icon a-icon-star a-star-5 review-rating', 'review_body': "I change my filter on the first of every month. Call me OCD if you will but having healthy air to breathe is nice. My allergies kick my but if I don't change it regularly. The other advantage to keeping your air clean is that it helps to keep you AC or heater working better."}]
