Filtrete12x24x1 AC Furnace Air Filter, MERV 13, MPR 2200, Elite Allergen, Bacteria & Virus Filter, 3-Month Pleated 1-Inch Electrostatic Air Cleaning Filter, 2-Pack (Actual Size 11.69x23.69x0.78 in)

These air filters cost more than their competition, but they are higher quality because they have lots more tight folds, and they're thicker, so a much larger surface area is working to provide better air quality for you. I would have given it 5 stars but the price is a bit high, even considering the higher quality.

Good product and fast delivery, well packaged.

It works, what else can I say. Be prepared to be traumatized when you see how black it gets in three months

I always buy these, the works best for me

I live in the high desert. This thing filters out so much dust. I also have a lot of cats/dogs (all rescues). This also takes out pet dander from the air. Don't believe the three month advertising. You'll probably change these out once a month to six weeks.

I receive these several months ago and believe they are the really product. ( I only add this because people said they receive fakes)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.

These filters seem like good quality. They are a really, really tight fit in a 14x24 space. I got them in but it required some force
