Why pay $300+ for something you can build yourself. I built this air cleaner for around $60. I already had the lumber and got the blower for free. The filters are 20×25, so that’d what size the box is also. If you plan to build one of these make sure to get the filters first and then build the box around them….much easier than trying to find filters to fit your box. On the intake side i have a 1” filter followed by a 4” filter and then on the output side i have a 1” filter. There is a 3/4” piece of MDF between each filter. The 4” filter is a MERV 12 filter and is effective to .3 microns. It’s also pretty expensive (for an air filter), $32, so that’s why I have a 1” filter in front of it…my hope is that the 1” will get a good portion of the dust and the 4” will get the rest but wont get used up too fast. I just finished so i haven’t used it yet except to test that it works. I have a remote for it since it will be hung from the ceiling and I have 10’ ceilings i need to be able to turn it on and off with ease.
Its not going to win any design contests but it works. :)
Thanks for looking.
I added a divider inside to separate the intake from the output. i didnt measure the airflow before i did that so i am not sure if there was any performance inhancement. I cant imagine there not being any improvement since it cant suck in air from the output side.
