Topic tags/keywords: question

Today someone, very nicely, gave me an almost new furnace blower to build a shop air cleaner.
This thing in high speed blows some serious air.

I stopped by my local Lowes to buy air filters to start to build my air cleaner. They carry only two types of air filters in this Lowes ( I was told several times that this is the smallest Lowes in the the USA).
I wanted to buy 3M Filtrete filters but they do not advertise any rating that I can understand, like Merv rating.
Instead that have MPR rating.
I found this page which tries to explain the correspondence between both ratings:

http://www.iaqsource.com/article.php/comparing-3m-filtrete-filters/?id=19

I knew that 3 M Filtrete filters are expensive, but ii did not know that they were that expensive!
The Largest one with the highest MPR rating is over $30.00 a piece!

Which filters do I need to use and which one I can do without?
(I understand that the highest rated and most expensive one do better job at cleaning the air but do I need it?)
Would I be better off buying a 1 micron filter from grizzly and use it instead?
Thank you.
Bertrand

Thanks for this post Bert. I’ve thought about using cheaper pre-filters and looked for washable filters. Haven’t found anything helpful. -Jack

In my shop made ambient air cleaner, I use 3 filters:
1st= generic pre filter
2nd= This 3m Filtrete filter from the HD
3rd= this filter from Grainger

Each filter gets progressively finer filtration.

At work we have perfectly good HEPA filters that we throw away but my boss refuses to let me have any of them
