Honeywell HAC-504 Replacement Filter for Honeywell Humidifiers

Fits HCM-1000 Series,HCM-2000 Series, HCM-500 Series,ECM-250i Series,HCM-600 Series,HCM-300T & HCM-310T

Tried to purchase this filter locally and could not find it even at the store that the humidifier was purchased. Found it on the web and it is the correct one. TY

i got a filter that says "best air" instead of honeywell

in the past i used to get honeywell filters

looks nothing like the pic either. instead of blue it has aluminum mesh ( thats right ! ) on the outside.

at first i thougth i got wrong filters then i read on the box that it does fit the same honeywell models as HC-14 so whatever ... haven't tried it yet but i assume it works lol

The quality is very good. The product is what I'm expecting based on the specifications that was written in the web.

nice when you find a good selection of utilitarian stuff that you need to constantly replace at a good price, also shipping is fast. this is the 2nd time i bought this filter here.

We run two humidifiers all year round here--it's dry in the desert--and these filters are MUCH better than the reg ones. It's worth a little more to get these. That blue stuff on the outside helps them last longer and filter the air better.
