How to Choose an Air Purifier for Your Basement
Before we get to our ‘Best Air Purifiers for Basements’ review list, we have to talk about certain tips which can help you buy the best product on the market. Not every air purifier is the same. That is why you need to look for particular features and specifications to invest in a worthwhile product.
You need to look at the filtration or purification system featured in an air purifier. If you want to get rid of pollutants, you should opt for a unit with a HEPA filter.

Mode of Operation
You should opt for an air purifier that is easy to use. No one likes to waste time trying to figure out how to properly make an electronic device function.
Another thing you should look at is the level of maintenance required. How many times will you have to change the filter? That is an important question to ask when you are looking to invest your money in an air purifier.
This might not be a big thing for some, but if your basement also serves as a recreational room or a bedroom, you should opt for a unit that is quiet while it operates.

Benefits of Investing in a Basement Air Purifier
Don't think that just because you don't visit the basement often, you don't need fresh air down there. Due to basements generally not having the best ventilation systems, they are vulnerable to stuffiness and mold.
Odor, mold, and dust are major issues you need to handle if you decide to make your basement a recreational area or even a guest bedroom.
Adding an air purifier to your basement (from the ones mentioned in our list) is an excellent way to do away with a number of problems and increase the quality of life in your house.
Clean Air Throughout the House
Many internal cooling and heating systems make use of air from the basement. This means that if there are allergens present in the basement air, they have a higher chance of entering the rest of the house. Having an air purifier in the basement keeps the air clean to ensure the rest of the house has safe air for you to breathe.
Gets Rid of Mold
No one wants their basement to have mold. With a quality air purifier in the basement, you can get easily get rid of mold spores. This will allow you to prevent a mold problem in the long run.

Many of us can’t always remember to dust the basement or don’t have the time to go down there with a duster. However, by having an air purifier in the basement, you can keep dust buildup at bay and ensure your house is clean from top to bottom.
A quality air purifier has filters which kill viruses, bacteria, and other pollutants. With germ-free air circulating the basement, you can be at peace with regards to your household staying healthy especially if the kids (with asthma or allergies) like to play in the cellar.
What Makes an Air Purifier Great for Basements?
Typically, basements have problems with air quality since they breed Volatile Organic Compounds (VOCs), dust, stagnant air, and molds. Therefore, with little to no air infiltration within such a humid environment, the piling up of such elements results in low air quality.
Air purifiers have some of the following features that help in improving air quality:
Carbon Filters for Removing Pollutants
Basement air purifiers can get rid of many pollutants found in the basement, such as VOCs and dust particles through the use of carbon filters. These purifiers have different filters that can capture up to 99% of the contaminants that are as minute as 0.3 microns.
Ionizer for Improved Air Circulation
If your basement does not have a door or windows, then the air in that area is usually stuffy and stale. Air purifiers would help circulate the air within the space and in temperature regulation, which improves the overall circulation of air in the area.
To achieve this, the ionizer discharges negatively charged ions that attract positively charged dust, pollen, or other pollutants. The added weight makes them fall to the floor, leaving only the light particles that the air purifier can work on easily.
UV Light for Removal of Molds
Most basements are breeding grounds for mold spores since the spaces usually have poor ventilation, are dark, and usually very damp. However, with air purifiers, the mold spores can be removed by sucking them up inside the filters and then destroying them using UV light.
Basement Air Purifier Tips, Tricks, and Hacks
After buying a basement air purifier, in most cases, you shouldn't put it exactly at the center where it is easy for it to disrupt your movement. It is advisable to put your air purifier close to the center if possible, instead of a corner. Doing this will ensure that there is a lot of air circulating near the device, enhancing its efficiency to clean the air in the space. There will be fewer interruptions since you won't be moving near it quite often.
Avoid Switching off the Air Purifier
Do not only switch the air purifier on when you feel you need it. Air purifiers perform best when they are left to operate all day and every day. The longer the unit is on, the better it performs and the cleaner the basement air becomes. There will be no build-up of contaminants in the space.
Check the Filters Frequently
For optimum performance, you will need to ensure that the filters of the air purifier are not clogged up with pollutants or trapped particles. Therefore, it would be best if you ensure that your filter is clean most of the time as this will help enhance its efficiency in cleaning the surrounding air.
Types of Air Purifiers That Are Great For Basement Use
Here are some types that work well in the lowest level of your home:
High-efficiency Particulate Air Purifiers (HEPA Purifiers)
HEPA purifiers are best for the removal of particles in the air. The particles are trapped on the filter and can't flow out back into the basement space. Due to the non-particulate nature of odors, HEPA purifiers are unable to clean the air of any bad odors. As such, they are most suitable when used together with other types of air purifiers that can clean out the odors.
Ultra-Violet HEPA Purifiers
HEPA purifiers with UV light are a good option in basements prone to dampness that would cause the proliferation of mold. The UV light kills any mold particles or bacterial growths that collect on the filter or are in the basement within its proximity.
Activated Carbon Air Purifiers
When used in the basement, these air purifiers are good for removing pollutants by chemically absorbing Volatile Organic Compounds that cause odors. It is important to note that some VOCs are odorless and as such, you should always have your Carbon filter air purifier on as much of the time as possible.
You should also check that the weight of the carbon in the purifier is well on the higher end compared to the rest of the purifier. This is especially important because the carbon filters trap these gases and may become saturated, leading to zero absorption or the "unsticking" of the initially trapped gases such that they flow back into the air.
Basement Air Purifier Comparisons
Hopefully, these comparisons will help you in your decision process:
Air Purifier vs Dehumidifier For Basement
Both air purifiers and dehumidifiers are excellent devices that can help enhance the quality of air in the basement by eliminating contaminants or humidity within it. Purifiers remove the gases or particles in the air while a dehumidifier lowers the air humidity levels by reducing the moisture in the air particles it attracts into it and releases back into space.
An air purifier circulates the air by capturing airborne contaminants such as pollen, smoke, and dust. It can also eliminate chemical or musty odors.
A dehumidifier cleans the air by sucking in the moisture within it, reducing humidity. They also kill microbes and molds due to the electrical heat they generate within the unit.
Germ Guardian vs Honeywell
Both of the air purifiers can trap up to 99.97% of the air particles up to a size of 0.3 microns. The filters also have activated carbon that absorbs odors and other particles in the basement.
The Germ Guardian air purifier has a room coverage of about 153 square feet. In comparison, Honeywell has a room coverage of 170 square feet, which makes it more suitable for greater room coverage than Germ Guardian.
The Germ Guardian has a 3-in-1 filtration mechanism that includes UV light technology, a charcoal filter, and a HEPA filter. The Honeywell purifier has four levels of cleaning but does not have UV technology.
How to Clean a Honeywell Air Purifier
1. Start by removing the outer grill to access the pre-filter
2. Use a vacuum cleaner to remove all the debris captured on the grill
3. Use a HEPA vacuum to clean the pre-filters. In the end, ensure the pre-filter is as clean as possible. If it doesn't, then you may consider replacing it especially if it has served you for about a year
4. Use the same HEPA vacuum to clean the HEPA filters of the air purifier. Ensure you have captured the spaces in between the HEPA filters to remove every particle captured in there
5. After you are done, return the pre-filter and the grill. Ensure they are intact.
Be sure to watch the video below for a detailed process of the steps we have just described above.
How to Clean a Germguardian Filter
1. Carefully follow the dismantling process of removing the filters
2. Dust off any excess dust in the filters
3. If it is a washable filter, clean the dirt and dust on the filter while ensuring that water is at medium pressure to avoid damage. Wash both sides of the filter.
4. In case the HEPA filter is non-washable, use a vacuum cleaner on a low setting. Ensure that you have run the hose or brush over the filter's entire surface to remove dust from all the corners
5. Place the filters outside to dry. Ensure they completely dry before placing them back
6.Follow the manual keenly when reinstalling the filter in the purifier.
Investing in a trustworthy (quality) air purifier for a basement is recommended if you don’t want to deal with mold problems. Furthermore, such air purifiers ensure you have safe and fresh air to breathe whenever you go down into the basement or even as your HVAC system pulls air from the surrounding area.
We hope our ‘Best Air Purifier for Basements' list will be able to help you make an informed buying decision. Take your time and get the air purifier that meets your needs.
