Durable Design

The performance of any machine is almost decidedly tied to the way the product looks in general. The Honeywell HCM-890B Humidifier features a simple smoky black design. It’s not the techy kind of units. It’s decidedly easy on the eye as well as it is to use. Yet, looks and feels like a sturdy unit. You best believe that it will last in the family for the long haul.

The fact that it offers a 5 year shows how durable this unit is. I like that the manufactures are able to stand with their product. Most other units only offer 1 year coverage.

Antimicrobial treated filter​

Tap water has a high mineral content. These mineral impurities usually emit alongside mist from your humidifier. The white dust found on furniture and curtains is the impurities emitted in the mist. This dust is hard to clean. It always damages the furniture.

The Honeywell HCM-890B Humidifier comes with uniquely designed replacement filters. This ensures that only clean mist is emitted. These filters effectively capture pollutants found in water. This prevents white dust deposit. And, improves your humidifier’s performance and output.

You’ll be pleased to learn that the filters are antimicrobial treated. They inhibit growth and transmission of algae, mold and bacteria. You’ll always have clean, bacteria-free air to breathe.

Self-Regulating Evaporative System

Its built-in adjustable Humidistat provides automatic humidity control. Maintaining the right humidity balance becomes as easy as flipping a button. No more wrestling with the harsh, dry winter air.

It guarantees complete and even humidification. Improvements in your rooms’ moisture content soon become apparent. Plants and wooden furniture do better. And, you are able to breathe and sleep more comfortably

Frequently Asked Question

Q. Is this safe around electronics like home audio receiver or the T.V? Also, does it warp wood or rust metal in the room?

A. I run this unit in my living room. It has not done any damage here. I think it’s for the fact that you get to control how much moisture output you get from it. Even so, the only water residue I ever saw was this one time when I was transporting it to the bed room and there was a drop on the floor. I suppose this would have cause damage if a significant amount had fallen on one of the electronics. But, I cannot really see this happening. It is a sturdy unit. If you are still concerned, you should call their customer relations department at 1-800-477-0457. Hope this was helpful.

And, it’s good for homes with children around. The Honeywell HCM-890B is designed to cover an extra-large area. It’s intended to use for multiple rooms.

I love this unit for three things mostly; effective humidification, long-lasting operation and silent operation. It’s perfect for homes with a small to medium size living spaces.
