Filter Vs No-Filter Humidifier
The basic difference between a no-filter humidifier and a commonly 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 humidifiers (with wick filter or permanent filters), it is important that you clean and change the filter as soon as they get saturated. Failing can cause a 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 do not include filters they are not much powerful in filtering out the debris, mineral particles and harmful bacteria from the water.
Can You Run Humidifier without Filter?
If you are trying to ask that “do you need a filter to run a humidifier?”
The simple answer is, no it’s not necessary to have a filter in your humidifier unit to run. Which means you can surely run a humidifier without a filter.
Filters are usually required in evaporative cool mist models. These self-cleaning humidifiers help in filtering out the moisturized air that comes out of the machine making them clean and healthy to breathe.
Ultrasonic cool mist humidifiers that work with tap water also requires you to have a proper filtration system to deliver a cool mist of clean air.
Models that do not come with filters should be used with purified distilled water to avoid the possible risks and damages.
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 an 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 a high amount of dust or allergens around you, it is best to consider using a high-quality premium grade filtered humidifier rather than a filter-free unit.
✗ When your tap water contains much salt or minerals
Using a filterless humidifier is generally not recommended when there are too many 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 a humidifier
Adding inhalants – like Vicks liquid in a humidifier – is a great way to relieve baby cold and other seasonal allergies.
But as filter-free 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 a 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.
Features to Consider when Buying A Filterless Humidifier
Modern filter-less humidifiers are available in various forms like they can be warm, cool, or ultrasonic. Additionally, they may have many smart features.
Although all the features are not useful, there are a few that are important for your use. Some of the most common ones you should look at are as follows:
First of all, before purchasing the humidifier, it is important to think about where and for whom the humidifier will be used.
If you want to use it in a child’s room, then select a humidifier with cool mist variety (as they are completely safe and don’t have any risk of accidents with hot water).
You should choose a cool mist filter-free humidifier that is easy to fill from the top if you are placing it in an elderly room.
Warm mist and ultrasonic humidifiers have no fan to blow the vapor into the atmosphere so they are the quietest humidifiers.
The noise in humidifiers is mainly because of the fan. And this noise varies in humidifiers depending on the speed you choose.
On a slow speed, the fan will whisper-quiet but at high speed, it will be loud and disturb you when you are sleeping.
You should test the humidifier before buying to check their noise level. Warm mist humidifiers may make some noise but they do not make so much that it will disturb or distract you from your work or sleep.
If you have no problem with noise by a running fan then purchase a humidifier having an operation noise of less than 30dB.
All humidifiers don’t have this feature. This feature of humidifiers maintains a healthy moisture level in your home automatically.
Hence it is good to purchase the humidifier in which the humidistat turns off the machine when the desired humidity level gets reached.
4- Auto shut-off
The auto shut-off feature avoids the risk of the humidifier breaking down. Normally, the water reservoir needs to be refilled every 2 to 3 days.
So, if you don’t keep on checking the water levels, you may face problems. Therefore, the auto shut-off feature preserves your humidifier from burning out.
5- Night Light
Some humidifiers brands have interchangeable night light settings while some humidifiers have power light indicators that act as a bright beacon in a dark room.
If you are a light sleeper then place the humidifier where you won’t be disturbed by the light, or you can also choose a humidifier that has a feature that lets you turn it off.
6- Coverage area
When purchasing the humidifier check the maximum coverage capacity. Generally, the medium-priced humidifiers have a coverage area of roughly 200 to 500 square feet.
More expensive humidifiers have a double or triple range than that of the medium-priced.
The mist output will tell you the capability of each unit. Higher the output the faster your spaces reach the correct humidity.
So, if you are looking for a high capacity humidifier, then you should opt for a whole-house humidifier which can easily meet the need of everyone and it also works as a money saver, as you no longer have to spend in buying another one.
7- Water Tank Size
The water tank size has the same concept as that of the coverage area and capacity. The size of the water tank will tell you at what time you have to fill it.
Most humidifiers can run for 2 to 3 days’ capacity if they are operated at their lowest setting while some humidifiers can last only for a few hours, which is frustrating especially if you have to run it for a whole night.
Some of the units also come with a water tank indicator. This indicator of the humidifier tells you to refill the reservoir when the tank drains off.
8- Ease of Filling and Cleaning
Many humidifiers are difficult to refill and when fitting the water reservoir, spills are common.
So, it’s essential that you check that the tank used in a humidifier is easy to remove and refill, especially when you are buying a humidifier for the elderly.
To avoid harmful bacteria entering your home environment, the maintenance of your humidifier is also very important.
Some filterless humidifiers have quirky shapes and it is very hard to reach places for their maintenance.
Therefore, when buying you can read the reviews to check the ease of cleaning, working, and their complaints – the cleaning of the unit should be effortless.
9- Aromatherapy Options
Many people like the soothing qualities of aromatherapy oils. From these types of humidifiers, they can humidify and scent their rooms with medicinal additives like lemon oil, tea tree, and many others.
You can take two benefits from this, first, the vapor can relieve sinuses, second, the essential oils open the airways making it easier to breathe.
Aromatherapy oils also lower stress levels, ease the level of depression and acts as an aid to mental wellbeing.
A filter-free humidifier can be purchased between $30 to $300 price range.
If you have the money in hand you can buy humidifier of any price, but if you don’t have enough money to spend then purchase a humidifier within your purchasing capacity.
If you have only a small coverage area then purchase a small unit humidifier and save some money in the long run. You can purchase such humidifier at the lower prices.
If you want to purchase a whole-house humidifier then you can buy a larger capacity humidifier.
But remember, they aren’t cheap. You should also consider the impact of a furnace humidifier at your indoor air before installing it.
So, check out the price of different humidifiers and go for the one which suits your budget, requirement, and preference well.
Overall, filterless humidifiers are absolute things to have in your home, especially if you have elders or kids at home.
Filter free humidifiers are offered at an affordable range, hence you can choose one that suits your home and family requirements without thinking as overboard spending.
Regardless of which humidifier you choose (filtered or non-filtered) care that you take proper steps in cleaning and maintaining them to avoid any risk they can pose.
Do not forget to read and follow the advice as suggested in the instructions manual to get the risk free humidification without any hassle.
