AC Infinity Inline Filter Box 10" with High Efficacy Filter, Whole House HVAC Filtration Kit, Fits 10-Inch Inline Duct Fans for Fresh Air Intake and Ventilation

I live in an area plagued by wildfire smoke and every year gets worse. I live in a Valley so temperature inversions are common and many of my neighbors have wood buring stove and some even illegally burn thei household garbage. I have indoor air cleaners which keep my indoor air quality index (AQI) very low, 1 to 4. However, Carbon Dioxide (CO2) levels get very high, especially in the bedroom when it can reach as high a 1400 ppm in the morning. Anything above 1000 ppm can cause headaches, fatigue, and other health issues. I assembled the system pictured it consists of the following: * AC Infinity Inline Filter Box fitted with Filterbuy 12x20x1 MERV 13 rated filters * AC Infinity Cloudline Pro S4 Inline Duct Fan * AC Infinity Flexible 4-inch Aluminum 4 layer HD Flex Hose (25') * Broan-NuTine 465B 4" to 5" Duct Adaptor * Gulrear Portable AC Window Vent Kit 5" I assembled these components and it allows me to draw in air from the outside, filter it, and disperse into the room. The 25' hose allowed me to place the outlet just below the top of the ceiling where monitoring have indicated is the best location. I use the IQ Air Airvisual Pro N1 indoor air quality monitor in the bedroom to track the AQI Index and most importantly for this purpose, the CO2 level. Prior to installing this system my highest reading in the morning averaged 950 ppm. Now I average 650 ppm. My 24 hour/day monthly average went from 735 ppm to 588 ppm. I am very pleased with the performance of the system and achieved my goal of reducing CO2 levels when I am unable to open the windows due to unhealty outdoor air quality. The AC Infinity products are of excellent quality and the inline Duct Fan is very quiet. I leave set at the 5 (out of 10) power level and it is very quiet. The combination of my air cleaner and the AC Infinity fan makes a great white noise level for restful sleep. In the pictures you will see how I have hidden some of the components under a chair. You can also see the hose outlet hidden behind the flower vase on top of the armoire. Update: Condensation inside the filter box was a concern, but with outside temps since installing in mid-October ranging from 65° to 22° F we have had zero moisture build up inside the filter box. Dry as a bone.

After installing an ERV, I noticed the intake air is not sufficiently filtered and that caused PM 2.5 particle counts to go up in the house. This filter is a great solution and I placed it before the ERV to filter the intake air before it reaches the ERV. This has dramatically reduced PM 2.5 particle count back to normal range. It's easy to install and is very solid. It doesn't come with any means to mount the filter or hang it. It's also not insulated so it can condensate if outside air is much colder than inside. I was worried about the box but it was well packaged. Finding the right filter for the 4 in and 6 in version might be a problem, but I think the Home Depot HDX 12X20 MERV 13 filter should fit based on the size of the filter online. But I am using the provided filter at the moment.

This thing is pretty solid, doesn't feel cheap. Remember to use 11.5 x 19.5 x .75 as a replacements. Its light enough to rest on top of a cheap 2x2 tent, maybe inside with proper port placement but for sure on TOP of it. First week this is catching little stuff that finds a way around the outside intake port. Second week I noticed a spider web on the filter side but not after, way better than finding webs in my grow and thinking I have spider mites. So after two weeks I don't think twice about buying this on a budget, its now a requirement to me like a carbon filter, it creates a peace of mind.

Like stated, it’s a nice filter holder. Built well. Down side is that ac infinity doesn’t sell a replacement filter that I know of. Had to measure out the one that came with the holder and get replacements from the hardware store.

It is rated at 10 meaning it will remove any pollen and prevent cross contamination. Probably the easiest filter to setup for any breeding tent. Highly recommend

I took a risk (according to other reviews) and purchased one of the returned ones. Turned out good! Very nice build and the supplied filter is super high quality. FYI, there are two standard 12x20x1 sizes on the market...the two have different actual/nominal sizes. Bought the ones with a nominal measurement of 11.5x19.5x0.75 (as the manufacturer says to do) and they fit just fine (smaller than the o.g. but still work).

Great build quality. Would get again.

MASTER BEDROOM HAD RETURN AIR FILTER 10 FEET UP WALL AND HAD TO DRAG LADDER IN HOUSE TO CHANGE FILTER. INSTALLED THIS IN FLEX DUCT AND NOW I JUST PULL DOWN LADDER AND WALK UP TO HOUSING AND CHANGE OUT.SUPER QUALITY

Keine Pollen vom Nachbarn mehr , die meine Pflanzen Samen lassen. Wirkt auf den ersten Blick sehr gut verarbeitet. Es ist mein erstes Produkt von AC Infinitiv und ich bin überrascht wie gut es ist.

Bit pricey but did the job. Keeps intake air clean but needs filter replacing often. Can tell its decent durable build as its metal. Not too noisy however it does have that familiar air ducting noise.
