Hi all
The blue filter in my Lunt BF1800? had gone a tad funky - I have already had a replacement one forwarded (no issues there) but I still have the old one. Pic below.

Is there any basic way of cleaning it - may be useful as a spare.
Thanks in advance.

Matt CLR I put mine in a small amount for a minute or two wipe clean with a tissue and rinse with distilled water.If not clean I repeat the process.
