Precisionaire Filter Poly SYN 16X25X1 031949145163

This item is a case of (12) Merv 8 rated furnace filters which cost less than $3.40 per filter (including shipping charges) and is a much lower cost than most other brands (such as Filtrete). A Merv 8 filter should be able to filter out most common particles in the air like pollen, dust, lint, pet dander, dust mite debris, mold spores and are better performers than the regular fiberglass filters. The higher Merv rated filters can filter out even more microparticles from the air, but the higher filtration efficiency could possibly reduce the air flow into the filter and put a strain on the heating/cooling system. This filter is made by Flanders which also sells at the local Home Depot stores. Flanders is made in the USA while Filtrete filters are made in Mexico. Flanders packages the filters with different outer packaging between this model and the ones sold at Home Depot. These filters have a white cardboard backing while the ones sold at Home Depot have a brown or white cardboard backing. Oddly, the Home Depot description of the brown and white cardboard backing filters have the same Merv rating of 8, but have different per unit cost. The brown one is $2.58 per unit while the white one is $3.97 per unit (brown model number is 87355 and white model number is 84855). Prices current as of April 18, 2013. The model number of the ones that I bought here at Amazon is 84858. Also, the outer packaging of this model lists filtering mold, bacteria, and virus carriers which is not listed on the Home Depot models. I also noticed something different when I purchased the filters on this site. The price dropped a little when I returned to the product page a second time after first finding the item. It appears that one of the merchants dropped their price based on a second visit from a prospective customer. But, the price would go back up a bit on subsequent visits to the same product page. Evidently, some kind of tracking is occuring on this site and the merchants have programmed their listings to react to it. Nonetheless, if you want to save a visit to the hardware store, this filter is a pretty good deal for a case of 12.

We have used these for several months now. Dust in the house has been reduced by at least 75%! However, on the order we just received the box was dented and two of the filters were damaged. Unfortunately, Amazon will not permit partial returns or adjustments on this product.

I have used these filters for years. They are great and reasonably priced.

I purchased this based on several customer reviews....I agree and am very happy with the performance of this filter. I will continue to buy and use these filters as I am very pleased with their performance. They are one of the very few filters which actually last up to 3 months in my furnace...I do place a cheapo 49cent filter in front of this one, which I change about every month, that will catch the larger air particles, but have found doing this greatly extends the life of these Natural Aire filters, without adding to the strain on the blower motor. Highly recommend!!

I use to buy these at home depot for around $9 a filter. I recently purchased 12 of them for under $4 each. That is a much better price. The performance of the filter works very well. I have bad allergies so I usually know when the filter needs to be replaced based upon how I feel. I have been getting around 3 months out of each of these filters. When I first moved into my house I had to have the filter housing worked on because not all of the return air was being filtered. After that, I noticed that my filters would only last around a month then but as time has gone by they last much longer.

This is the only brand of furnace filter use. My furnace company even said it was very good. I change my filter every 30 days.

Inside of filter broke away in June and I pulled it back out but today AC was making a loud noise and I noted the entirety of the inside had disappeared into the AC unit. Technician will be here tomorrow then I will throw away my remaining filters.

These are less expensive and of higher allergy protection quality than the ones I can buy at the big box stores near me. It is also convenient that I can buy an amount that lasts the entire year. Although they say they last 90 days, I change them once a month.
