The 8 Best Humidifier Filters for Cleaner Air: A Guide

If you use a humidifier regularly, you will find that it may dry out your hands and not be as effective as usual after some time and unfortunately, many people are unaware that a filter is essential to using a humidifier.

Of course, humidifiers are a great choice if you want to keep your house dry but they may also dry out your skin especially if you live in a desert area but a filter should be able to keep that from happening.

Some people like to use humidifiers as a spa treatment since the water in a humidifier is really concentrated, especially when it’s heated.

One thing to keep in mind, however, is that putting essential oils in a humidifier, for instance, is not really a good idea.

While it sounds great at first, they can actually clog the filter and even erode the plastic tanks or fan mechanisms.

If that’s the effect you want in your house, it’s a better idea to simply buy a separate diffuse that allows for essential oils to be added.

Just keep it away from your humidifier and you’ll get the best of both worlds.

With the right setup, you will feel like you’re at a spa every day!

Of course, their main use is to increase the amount of steam produced by one’s heating system.

On the other hand, others may use their humidifier to reduce the amount of humidity in their home as well as keep a constant temperature.

When used in conjunction with your air conditioner, it can keep your house from getting too cool or too warm.

Of course, the effects are generally dependent on weather, being able to provide a dry environment for rainy areas and add some much needed moisture in areas that are always hot and windy.

Soon after getting a humidifier, however, you will realize how important filters are.

This is because while it can make breathing easier, a humidifier might end up causing the humidity to drop too fast, making it harder to keep the moisture in the air.

Thankfully, the right humidifier filters for your furnace can fix this issue, ensuring that your humidifier works at the most optimal level.

The filters will also remove the dust and contaminant particles from the air, preventing people from getting sick with respiratory problems as often.

Many people get humidifiers to keep the bedding and furniture free from bacteria and clean since these are surfaces that often get covered in dust and get dirty fast.

In the absence of a humidifier filter for your furnace, airborne particles will get into the air and circulate all throughout the rooms of your home freely.

The good news is that humidifier filters are easy to find.

They are often sold either separate or as part of convenient sets that often even include a humidifier, in most online stores.

The best idea is to purchase filters when you first get a humidifier since humidifiers can store them when not in use, ensuring that they will last longer as well.

Some humidifiers have the filters attaches when you first purchase them but you will still be able to get more after when it’s time to change it.

If you wish to keep your air as clean and healthy as it can be, getting filters for your humidifier is really important, especially if you are someone who often deals with respiratory problems caused by airborne bacteria and other small particles like dust.

If this sounds like you and you want to know more before, here is a comprehensive guide to buying humidifier filters!

As you might have figured out by now, humidifiers are meant to add some needed moisture to the air and help people breathe better.

The filters inside a humidifier are there to block pollutants and prevent bacteria, mold and algae growth in the water.

The majority of humidifiers nowadays, use cool mist ultrasonic technology, which means they use ultrasonic sound vibrations.

On the other hand, regular humidifiers use high-speed rotating disks.

Regardless of the type of choose, however, it is important to know that the EPA recommendation is that you make sure to clean it every three days.

In the absence of clean filters, humidifiers will not be able to do their job right.

Filters are usually accessible and made from paper, clay and metal.

They hold water while the air blows across the antimicrobial coating, process during which impurities get removed and the spread of bacteria, mold and viruses is blocked.

While the filters don’t have an expiration date while in their packages, when you start using them, it’s recommended you change them after no more than three to four months since they become brittle and clogged over time.

Not only will they be useless at that point but they can also get contaminated with all kinds of impurities from the water.

In other words, it’s a good idea to change them every season or even more often if you feel like the air in your home is particularly dry.

When the time to replace your filter comes, make sure you get ones that fit your humidifier so check the specifications on yours to make sure you purchase what it needs.

Checking the product reviews is on the filters is always a good idea as well if you need more information.

Before we get to the list of products we have prepared for you, here are a few more quick tips you may find helpful:

– Unless the package says differently, distilled or filtered water is the best to use. This is because hard water can really degrade the filters.

– When cleaning the humidifier, make sure to empty the tank and use a microfiber cloth to wipe all surfaces dry.

– If you see the filter discolor a little with use just know that it’s normal and not a reason for concern.

– Some filters need to get soaked in water before use.
