The Filterbuy replacement air filter 18x18x1 (actual measurements: 17.75" x 17.75" x 0.75") ensures that your furnace, air conditioner, heat pump, or HVAC system is circulating the cleanest air possible to help preserve your budget and healthy lifestyle. MERV 11 synthetic media (comparable with Micro Allergen Defense MPR 1000 - 1200 & FPR 7) is recommended if you have pets or allergies due to its capability to trap 95% of airborne particles, protecting your home or business from smoke, smog, debris, lint, pollen, mold, dander, and other forms of dust without impacting air flow. High quality construction features an electrostatically charged design with 14 pleats per foot that captures more harmful particles and prolongs the products lifespan by three times that of fiberglass models. Plus, our industrial grade beverage board frames are paired with dual wire backings that significantly outperform traditional cardboard compositions by improving structural integrity with their ability to endure temperatures up to 200 degrees Fahrenheit and withstand exposure to moisture. Installation is also made simple with the addition of easy-to-understand arrows that help identify the direction of air flow and subsequently the way the filter needs to be placed. To top it off, all our components are 100% manufactured within the United States and designed with recyclable materials, providing an eco-friendly alternative to enhancing your air quality.

I have a 3 zone system that requires 4 different filters and found these to be the most cost effective.

Best convenient filters

Filterbuy

I was frustrated never finding my filter size in the stores, and even more frustrated cutting and fitting the adjustable types. The website made it easy not only to find the right size, but also explains all the different ratings so I could pick the right one. Shipping was quick and filter fit perfectly!

Fits like a glove

It works; you did your job right. If I am happy I rarely blow a horn. Only when unhappy do I ever explicitly communicate then insistently. Good facts for you to know when you next send review requests. Despite my absence of affect I am glad we did & will do more business.

fine service

I love having extra filters at my fingertips for several reasons: Where I live, there are days or weeks when there is more dust in the air due to weather, construction in the area, nearby highway traffic (Disney World is just down 75), a busy race track less than a mile from me; get the picture? Sometimes, the filter gets a real workout and I like to know that I always have a high quality filter that exactly fits my air return vents readily available. I value the use of the air conditioner because 90 degree plus days are normal here. A clean filter keeps the A/C functioning at it's best. Filterbuy never lets me down and the price is right!

A clean air conditioner filter is a must in Florida.

Took a few days to get, but they are what I expected. Seem to be of good quality, time will tell. They do seem to fit the return a little looser then the ones I had from big box store

Took a few days to

This company makes it easy to maintain the air quality of my home. No more running to the hardware store trying to locate the correct sizes. Very happy.

This company makes it easy

So far so good. Unlike the 14 x14 filters which arrived and were too small compared to other commercial 14 x 14 filters, the 18x 18 fit fine and seem to be of ok quality.

18x18 ok

It's on the same level as the basic Filtrete filter. I buy Merv 11 from them and it's nice and quiet. This one is as loud or louder than the basic filtrete filters I tried. Also, they don't fit tight like the filtrete filters, I guess that 1/4 inch makes a big difference. After I use these filters, I am going back to Filtrete by 3m. Sorry guys, I figure I would give you guys a try, just didn't work out.

It's on the same level

I'm aware of 3/4" variance but 1/2" variance is not acceptable and will never buy again. We have issues, one the filter is not snug to the frame and second, every time the system runs, it sucks the filter towards the frame making unnecessary sound. You guys lost my trust :(.

17.5x17.5 should not be sold as 18x18

The size of the filters no longer fit my system. Prior to my current order the filter - 18 x 18 x 1 has always beenactually 17 1/2 x 17 1/2 x 1; now they are17 3/4 x 17 3/4 x 1 and no longer fit.
