Round A/C Return Ducts Cleaning

[Earl II]

Okay, minor issue but just asking. We have had our Newmar Bay Star 3124 since March 2019 and the round A/C return ducts are in dire need of cleaning. Am I correct in my guess that they all have to have the four screws removed to get to the filters for cleaning? I see that there are disposable replacements on Amazon.

If they are like mine. Just pull the center grill out. They snap in.
Then if foam filters wash in sink and air dry and then put back. I have 2 sets to rotate out when cleaning.

Good to know. Thank you. I thought that having to unscrew the four screws was way too much but then I seem to make things like this too complicated.

You can also buy extra foam filters which makes it easier to just pop out the dirty one, replace with clean one, and then just clean and dry the dirty ones and store until needed.

These can be purchased on Amazon (if you are talking about the round ones) https://www.amazon.com/gp/product/B0...ACUNF955&psc=1 or go to any big box store, Lowes, Home Depot, Walmart, etc and buy several packages containing 2-4 foam looking filters that are for small ac window units. (Usually around $3 +-) Take one of your existing round filters and trace out the total number needed per the number of your ceiling return vents. This will determine how many packages to buy. Our previous 2004 MH had I believe (2) rows of ac vents that ran parallel with each other, one row each had a filter and the other row was where the cool air came out of. This filter material can be cleaned and reused many times. As described in a previous post, the plastic round louvered part holding the filter material can be removed by placing a finger in each side of the center round part and pull out. insert clean filter and snap back in. In our current mh, we have a combination of (2) round vents with filters along with (3) rectangular ceiling vents, each having (2) filtered sides. I bought several packages of the above described filter material and keep enough on hand for (3) changes at any given time. The plastic louvered vents can also be found if when/if replacements are needed for those that may break. https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1
