Does it need a filter?

No. It is filter-free and boils water to make warm mist, so there are no wicks or filters to replace.

How long does one fill last?

The 1-gallon tank runs up to 24 hours on the lower speed; the higher speed uses water faster.

What size room is it for?

It is intended for medium-size rooms, with coverage listed up to 1,000 sq. ft.

Is it good for a bedroom?

It works in bedrooms, but the boiling and gurgling noise bothers some light sleepers.

How often should I clean it?

Clean and descale regularly, more often with hard water, since mineral scale builds up in the tank and heating area.

Is warm mist better than cool mist?

Warm mist feels gentle in cold rooms and needs no filter, but it adds heat and uses more energy than a cool mist unit.

Our take on the Honeywell Warm Mist Humidifier HWM705B

The Honeywell HWM705B is a filter-free warm mist humidifier with a 1-gallon tank and two output speeds. It runs up to 24 hours per fill and is aimed at medium rooms. Unlike cool mist rivals, it boils water to release visible warm steam, so it needs no wick or filter to replace. Owners like the filter-free running and the visible mist; the common complaints are mineral scale buildup, gurgling noise and the need for regular cleaning.
