Hey folks, hope everyone's grows are going well! I decided to post my DIY intake filter because I think it's awesome, and it can save you a lot of money. While I was in the market for an intake filter, I realized how outrageously expensive they all are. So, I decided to make my own for $28. Please note that this is intended for an active intake.
First, I bought an 8" x 8" to 6" square to round register from Home Depot for $12:

Then I bought an 8" x 8" furnace filter and put it inside the register, $16:

I didn't do this part, but you can add a return grill from Amazon for $10 to make it pretty:

And there it is. With the grill it would be $38 total. That is way cheaper than any ready made intake filter. You may find one like the can filter for that price, but the shipping will make it around $70 minimum. Plus, the can filter intake filter is only MERV 4 filtration. With this DIY filter you can choose your own degree of filtration. If you want to make it even cheaper, instead of buying the 8" x 8" HEPA filter for $15, you can buy any size cheaper furnace filter and just cut it to size.
Hope this helps someone!!!

of doing what you can with what you got on the cheap
.. nicely done... You mentioned this is intended for an ACTIVE INTAKE??. Now I'm not sure and I'm definitely over thinking your briliant DYI invent.. but would you put an intake fan on top.. if so would this now be classed as an under cover scrubber.lol.. diy at its finest.. hey bro I couldn't thumbs up or like this so .....
