I have 2 Hunter cold water vaporizers Model 33222 that have metal mesh filters. Have been cleaning filters according to instructions, that is, soak in vinegar/water solution 20 minutes (I have soaked longer, even hours).

For some reason lime deposits WILL NOT BUDGE.

Have tried the following:

Strong vinegar/water solution long soak.

Limeway & toothbrush.

Boil in strong vinegar/water solution, soak, boil, soak.

Run vaporizer with 1/4 c. vinegar added to the water for a week.

Tried using a knife point to dislodge the deposits to no avail. Yeah, they get a little softer soaking but refuse to budge even with help.

Help!!! does anyone have the answer? Vaporizers are only about 6 weeks old.

Did not realize our water had that much lime, glasses, etc. do not show signs of it.
