Best Filterless Humidifiers and Buying Guide

Best Filterless Humidifiers and Buying Guide

Last Updated on

Humidifiers become essential in dry weather when the lack of moisture in the air can irritate your throat and nasal passage, triggering several allergies, and causing many respiratory issues. The sole purpose of all humidifiers is to add moisture into the air and to keep the humidity level of a room well balanced. Several kinds of humidifiers are in the market ranging from central humidifiers that regulate the humidity level of the whole house, to the portable ones. Portable humidifiers are further divided into several categories like warm mist humidifier, cool mist humidifiers, and ultrasonic humidifiers.

Some humidifiers use a filter to clean the water vapors before they are emitted into the air. The moisture is drawn up into the filter, and a fan causes the necessary evaporation. A filterless humidifier does not use filters and operates without them. Warm mist humidifiers do not need filters as the heat kills the virus and bacteria in water and they do not need extra additives.

 

Humidifiers with filter vs Humidifiers without filters

All kinds of particles like smoke, dust, or smoke can settle in the water of your humidifier. The filter in humidifier trap these elements and don’t allow them to enter in the vapors that are emitting in the air thus saving us from a lot of allergens. But these filters need to be constantly cleaned, and after a specific period, they need to be changed.

Humidifier manufacturers realized this inconvenience and developed humidifiers that do not need filters. These humidifiers use an electrostatic charge to remove the impurities from the water. Ultrasonic humidifiers that use the sound vibration to create the mist don’t use filters. Some larger humidifiers and evaporators offer permanent filtration trays that can be cleaned.

The humidifiers with filters use a fan for evaporating the water, so obviously they are noisier. While on the other hand, the filterless humidifiers are quieter as no use of the fan is involved. Changing and cleaning filters can be a nuisance, but with filterless humidifiers, you need to be more careful about the cleanliness of your humidifier.

Advantages of a Filterless Humidifiers

Quieter

Humidifiers with filters often produce a loud noise. The fans in these humidifiers can create some level of noise and can be irritating for some people. Especially if you are using the humidifier in a nursery, a quiet humidifier seems more appealing. Humidifiers without filter are quieter and no more waking up in the middle of the night with the loud noise.

Don’t have to buy a filter

The filter has a short span of life, and even though you keep cleaning them, there comes a time when you have to replace them unless you are alright with running a dirty filter. The humidifiers without filters are one-time investment, and you don’t have to buy filters from time to time.

Antibacterial Protection

The filterless humidifier uses the latest technology to use an electromagnetic charge to remove the impurities from the water. It prevents the growth of bacteria, virus, mold, or mildew in water. The water vapors coming out of humidifier are dispersed in the air that you are inhaling and the contaminated air can aggravate your allergies rather than comforting it.

Disadvantages of a filterless humidifier

Need to be Cleaned more often

Filterless humidifiers need more regular cleaning. Although all kinds of humidifiers need maintenance and proper cleaning, the filterless humidifiers can deposit the mineral traces in the base and need regular cleaning.

Emits White Dust

Ultrasonic filterless humidifiers emit white dust in the air along with the mist. If you are using tap water to fill up the tank of the humidifier, then the mineral deposits in water are also dispersed with mist into the air. This dust settles down on the furniture or around the room. It can cause dust allergy and is not suitable for people with the dust allergy. However, filling up demineralized water in the tank is a solution for avoiding white dust.

Costly

If you are using filterless ultrasonic humidifiers, then they can be a bit expensive than the usual humidifiers with filters. However, these are a one-time investment, and you don’t have to buy a new filter from time to time.

Types of Filterless Humidifiers

Many types of humidifiers are available in the market that does not use filters. Some of them are as follows:

1. Evaporators
2. Central Humidifiers
3. Steam vaporizers
4. Impellers
5. Ultrasonic Humidifiers

Central humidifiers control the humidity level of the whole house. As steam vaporizers use heat to boil water and bacteria or other pathogens cannot survive in boiling water, the steam vaporizers don’t need filters. Impellers are more child-friendly as they use the cool mist that helps babies or children suffering from congestion. Ultrasonic humidifiers use ultrasonic vibration to create the mist. Therefore, choosing a humidifier depends on your personal preference and budget.

Factors to Consider while Choosing a Filterless Humidifier

Many filterless humidifiers are available in the market, but there are certain things that you should consider while choosing a filterless humidifier for your room.

Capacity

The size of your room should be considered while choosing a humidifier. A humidifier that is built for a large area would make a little room damp in the same way a smaller humidifier in a large room would be ineffective. While buying a humidifier always read the specifications which mention the area it is designed to humidify.

Easy to clean

Humidifiers need to be cleaned on a regular basis, and a filterless humidifier needs even more care. While choosing a humidifier, take good care to choose one which is easy to assemble and clean.

Control

The more control a humidifier offers, the better it will be for you and your baby. You can adjust the moisture level and also the speed of the fan. Those with timer and auto-shut options offer more control and are more convenient.

Humidistat

Humidistat prevents your room to become over humid. It prevents humidifier to emit more than necessary moisture into the air. Humidifiers without humidistat may make your room damper. Investing in a hygrometer is also helpful as it allows you to keep an eye on the humidity level of your room.
