Humidity is a tricky thing to deal with. As the seasons go by and as summer turns into autumn and then winter, humidity levels tend to drop and rise uncontrollably. This may not seem too bad on paper but the fact that humidity levels have the potential to negatively impact not just our homes and immediate surroundings, but our health as well means that it can pose a serious threat.
From allowing for the festering of mold to aggravating ongoing respiratory issues such as asthma to even causing your lips to crack and bleed, a good household is a household with its humidity at ideal levels.
Thankfully there is a silver lining to this cloud: humidifiers. These nifty devices can keep humidity levels at their optimal points and won’t cost you an arm or leg to purchase. Better yet, the humidifiers we’re leaning for operate totally without filters.
This means you’ll be able to save on cost in the long run without compromising functionality! Just read on below to check out our take on the best filterless humidifiers in the market right now.

A Buyer’s Guide to Filterless Humidifiers
Not all filters are designed to accommodate large rooms. The options on our list that hover around a capacity of 1 gallon especially so. If you’re planning on using your humidifier in a large area such as a hall or office corridor, we suggest you look for options that can specifically accommodate for that.
Alternatively, you can also purchase several smaller capacity humidifiers and spread them out appropriately. That being said, if you get a large capacity humidifier, you can always scale it down, but the converse doesn’t not apply.
While most humidifiers are designed to operate at the quietest levels that won’t be noticed even by sharp ears, if you are a super light sleeper or are especially pedantic about any sort of noise, always check the dB numbers before making a purchase. You don’t want your humidifier to be constantly annoying you through the long days!
Nightlights make a fantastic addition for any child or adult suffering from sleeping problems. Calming, relaxing, and soothing to both the mind and eye, if you think you’ll benefit from having a nightlight, humidifiers surprisingly will be your best friend as many come pre-installed with them. Even if you don’t want them, you’ll easily be able to shut it off at any time. It’s a win-win situation really.
Frequently Asked Questions (FAQs)
Do I need to have an aroma tray?
They are totally optional. If you like certain fragrances and want a room to smell just like it, having an aroma tray will be a blessing to you. Likewise, if you prefer something more unnoticeable and neutral, you’ll be totally fine not using one as well.
Do I need to use a specific type of water to fill my humidifier?
Absolutely not. You don’t have to worry about carefully preparing boiled water or even purchasing entire packs of drinking water for your humidifier.

That being said, depending on where you live, tap water may contain certain chemicals and pollutants which can detract from your humidifier’s efficiency so do check on this first.

You should be refilling your humidifier before using it every time, but we get that this can be a little annoying for some. Allowing it to run until it is totally dry is fine to as most devices have automatic shut-down functions that rely on in-built sensors.
