PUREBURG 4-Pack HAC-504 Humidifier Filter Compatible with Honeywell HAC-504AW & Filter A Fits HCM-350 HEV355 HCM-710 Cool Mist Humidifiers and More

I use this filter in my humidifier (and have been for years) and never have any issues. They are consistent and reliable!

They work!

In my opinion, these are definitely worth it because going to the store you only get a quantity of one and there’s so much more expensive. The only downfall for me is I ordered the exact same kind that I need but they came a little tall. So I just had to cut them to size but they were perfect.

A lot less expensive than the name brand by Honeywell and they work just as well. I've had no issues with them in terms of fit or longevity. They appear to be an equal substitute.

I oder replacement part for my Holmes humidifier. Unfortunately it did not fit so I cut off an inch so it would work. I needed it so can sleep better being house is so dry. Other than being too tall, it works great

Easy to use

Work perfect in my humidifiers, perfect fit. Good value for the price. Will buy again.

This item is decent, but won't last as long as items with a bacteriostat built in (such as the Protec model). Yes, I used a bacteriostat in the water tank as well.

I like the price first and it works well

Très bon produit qualité prix

Great value for the money at a fraction of the price of the Honeywell filters.They fit my Honeywell machine perfectly.Plus they arrived a week earlier than expected.

I use these filters on my humdifyer every 30 days, they work very well

On first impression this product appears to be a good option compared to original filter. It works as well as the one sold under the Honeywell brand and at less than half the cost.
