What Reviewers Said About This Filterless Humidifier:


The Best Humidifier With No Filters To Deal With

After buying filters for years for my old water filter, I swore my next humidifier would be filter-free. I found this one on sale and it’s great! Very quiet and simple to take apart and simple to fill.


  • Our previous one required a filter and purchasing them was getting old as we spent more in filters than we did on the unit itself. 
  • I am using Brita filtered water, which I store up in gallon water jugs so always ready.
  • Mainly I bought this because of amazon reviews and the ‘no filter’ option.
  • Also, unlike others we’ve had, this has no replaceable filters to deal with.
  • No filters to change.
  • I really liked that it does not have a filter. (Our old and large Hunter humidifier has a large filter that gets disgusting and must be tossed every year or two.
  • Quiet, no filter, modern design, four settings.


No filters, which is awesome! I’ve had other cool mist humidifiers that had filters and involved elaborate cleaning procedures. None of that here.


  • No filters come with a cleaning brush, the plugin cord is an awesome feature that allows for a quick fill-up and cleaning if used several days in a row.
  • Easy to clean no filter needed. 
  • All in all, a terrific, quiet humidifier that requires no filters, is easy to fill, and works great. 
  • I especially like that there is no filter to deal with, making the build-up of mold, not a concern.
  • Plus, there’s no filter to replace so it’s almost an added bonus! Stop your search and buy this one. You’re not going to find any better!
  • Great not needing a filter = easy cleaning and less $ to spend.
  • It doesn’t require a filter, which makes it easy to clean and to use.


Just what we needed. Purchased for my children’s room as a previous humidifier broke when my daughter knocked it over. So far works great! Quiet and I love the “nightlight” settings.

The directional nozzle and not having to purchase filters is what really made me interested in purchasing.


  • This is filter-free and the nightlight is great.
  • The best part about this unit is there are NO FILTERS!
  • I love the design and the fact that it does not require a filter
  • Easy to fill and NO filters to mess with.
  • A big plus for detachable cord. A big plus for no filter
  • I love that there isn’t a filter! That was the biggest reason I wasn’t using one regularly before. This will be on every night this winter!
  • EASY to use. NO filters which make this cleaner, cheaper, and handy.


This is a super nice little humidifier at a reasonable price. After having an evap humidifier for years that churned through $13 filters every 2 weeks, I LOVE having a humidifier that doesn’t require a filter.


  • It’s so nice not to have to constantly change filters.
  • No white dust, no filters to deal with.
  • I really love that I don’t have to change a filter and worry about mold and algae getting pumped into the air.
  • We have had this humidifier since March 2016 and we love it. No filter to replace, easy to clean, and works great.
  • Best humidifier out there. No gross filters to clean or worry about mold.
  • I love that I don’t have to buy filters for this unit and it is very simple to clean and maintain.
  • There are no messy filters to replace.

“I also like the fact that unlike my old one that sprayed water into the air and made a mess this one dispenses a cool mist like a cloud.


  • It emits a cool mist so it’s more subtle than the warm humidifiers.
  • The mist is cool, not overpowering, and not “smoky” and you can turn the nozzle in the desired direction.
  • Perfect for the summer the mist has a cooling effect.
  • The mist is cool and it doesn’t make your house feel humid.
  • This little guy is awesome. It creates a cool mist in a completely quiet way. 
  • It also provides a cool mist, which doesn’t leave the area around the humidifier damp as other machines do.
  • The mist feels comfortable and cool on my skin.
  • It is small, quiet, sends out a cool-mist but nothing around it ever gets wet. 
  • The price is reasonable, it is very quiet and blows a very fine cool mist.
  • It gives the room a nice cool comfortable moisture instead of a damp feeling like humidifiers I’ve used in the past.

This is perfect because you fill it every night before bed, and you never have to worry about changing filters. Small enough to fit on his nightstand. And it drastically makes a difference with his sinuses.

  • This thing is WONDERFUL!
  • No filter, easy to clean, easy to fill, nice and quiet, customizable mist levels, and don’t even get me started on the VapoPads!

Reviewer Comments:


I really shopped around before buying this humidifier as I didn’t want to spend a bunch of money replacing filters (or even having to CHECK to see if they need replacing), because that’s just another thing I don’t want to keep track of.

I love the ease of use this has. It’s super easy to fill, I haven’t seen a leak yet, and it’s so quiet I don’t even know it’s on.

Best part is I no longer have static issues, dry nose, excessively dry winter skin and it’s a large reservoir so even on high it only needs filled once a day. Great purchase!


  • Other units I have need wicking filter replacement every season and the warm mist one stops working occasionally. This one needs none of it, just fill the tank with water and turned it on and there is mist.
  • This humidifier is excellent!
  • Lightweight, easy to clean (hole large enough to fit your hand through), easy to refill water, no filter hassle, and very quiet.
  • I really like this humidifier.
  • It doesn’t require a filter.
  • Also, it’s small enough to sit on my nightstand but still hold enough water that I only have to refill it every other night or every couple of nights (on high humidity!)
  • Quiet. Really super quiet.
  • It does not have a filter to worry about, so no mold/grossness of that to deal with.
