Filter Vs No-Filter Humidifier

The basic difference between a no-filter humidifier and a usual filtered humidifier is the absence of replaceable filters that makes the unit easy to clean and maintain.

Filtered humidifier units generally come with a removable and replaceable filter to remove dust, contamination, minerals, bacteria and viruses present in the water before the moisturized air is expelled out in the atmosphere.

While using these filtered humidifier (with wick filter or permanent filters), it is important that you clean and change the filters as soon as they get saturated. Failing which can cause serious impact on your health.

Non-Filtered humidifier (with no-filters) on the other hand comes with an electrostatic charge dish, cartridge or an antibacterial stick.

This acts as a built-in filter to demineralize the water and to help remove the impurities (minerals, bacteria and viruses) present in the water partially.

As there are no add-on costs of filters (or evaporated pads) to clean or replace, these units are often less expensive to buy and use.

However it is important to note that as these filterless units does not include filters they are not much powerful in filtering out the debris, mineral particles and harmful bacteria from the water.

When NOT To Use Filterless Humidifier?

Though using a humidifier, which does not contain a filter, is a trending idea; based on certain situations and weather conditions it is many times not recommended to use them at home.

Some of these situations may include:

✗ When you live in area with high pollution: Dust, pollen, pet dander and many other allergens can be a severe problem for many.

If you reside in an area with high amount of dust or allergens around you, it is best to consider using a good filtered humidifier rather than a filter-free unit.

✗ When your tap water contain much salt or minerals: Using filterless humidifier is generally not recommended when there are too much impurities present in your tap water or if you want to use hard water in your humidifier.

This is due to the fact that non-filtered humidifiers are not much efficient in removing these visible impurities or bacteria from the water.

These can hence cause further complex conditions especially for those suffering from respiratory disorders, breathing problems or allergies.

✗ When you have a sick infant or an asthmatic at home: Your sick baby or an asthmatic family member can be a matter of high concern for you.

As the germs, smoke and allergens present in the environment can make their condition worse, if not filtered out properly, you should definitely choose to have a filtered humidifier unit for them and not a filter-less device.

✗ When you want to use inhalants or aroma oils in humidifier: Adding inhalants – like Vicks liquid in a humidifier – is a great way to relieve baby cold and other seasonal allergies.

But as filterfree humidifiers are less efficient in filtering, it may interfere with the inhalant and can increase the chances of getting the air contaminated.

If you want to use some specific inhalant or liquid in your unit on regular basis, it is best to get a warm mist humidifier or vaporizer with filters.

These are highly efficient in filtering the air before misting thereby ensuring that you are benefited most with these inhalants.

Overall, filterless humidifiers are absolute things to have in your home, especially if you have elders or kids at home.
