DIY HEPA Filter (for less than $30, too!)

You guys never read my threads mad so I'll just get to the nitty gritty for those who can benefit.

• My allergies are really bad year-round. HEPA filters typically work, but there is too much trouble picking/buying one.

• I looked online for a DIY HEPA filter. I found this page: Box Fan Air Filter Air Cleaner

• It is basically a MERV 11 filter + 20" box fan. I was able to find both at Wal-Mart for less than $30. ($12 Boxfan + $12.88 3M MERV 11)

Here is my rig.

Initial Thoughts



- Moves more air than most Honeywell units I've bought



- I can pick what type of filter to use. I'm going to stick with a minimum of MERV 11 filters. I think 3M has purple ultra-pleated 1600 filters that can be used as well.



- You can easily attach a cheap sheet of absorbent carbon before the filter to remove odors. I have never needed one.



- Finding replacement filters is very easy.



- This gets around the guilt of putting a restrictive filter into the air handler and worrying about the fan burning out.



Will update with results in about a week.

Hardly. The units you buy at the store are the same idea but in a housing to hide the mechanism. With most of those units you pay $100 for the initial purchase and then $45 for replacement filters.



But hey if you want to waste your money, please feel free to do so.:heelclick

Yep. We use ones of these in the bedroom to keep the allergens down. Works pretty well.
