Your basement needs a quality air purifier to help you get rid of high humidity, mold, and odd smells. All you need is the best air purifier for basement at an affordable price to improve the air quality in the basement, limiting dust buildup. 

Usually, an efficient air circulation system is enough for maintaining the humidity level in the basement. But you can’t avoid mold, dust, dander, lint, different disturbing odors, VOCs with only cellar ventilation. An air purifier is the only feasible solution that can ensure healthy, clean, and odor-free air in the basement. 

Here, we will be informing you about the best air purifier for basement, so that you can make an educated purchase decision. Before that, let’s know what factors you should keep in mind when buying an air purifier. 

Things to Consider When Buying Basement Air Purifiers

As a general user, you may not know what to look for in an air purifier before buying. Our experienced team members are here to help you out. We have listed down all the important factors that determine the effectiveness of an air purifier while filtering the basement air. The key points are discussed in the below section.

Filtration System

This is the core feature of an air purifier. If you buy a unit loaded with additional features but without a quality filtration system, that will be a total waste of money. You must go for a true HEPA filter that is accompanied by an activated carbon filter and a pre-filter. This combination can remove both air particles and household odors effectively. A UV light facility is a bonus if you have it, but that’s not mandatory. 

Air Pollutant Removal Capacity

The capacity of a purifier depends on the type of filter and its CADR rating. CADR refers to the clean air delivery rate that tells a user how quickly the purifier can replace the polluted air with purified air. We suggest you use a purifier with a CADR score of at least 100 cubic feet per minute. Besides, a top-class purifier can remove up to99.97% of air pollutants that are as small as 0.3 microns. 

Coverage Area

This is a crucial factor that dictates the efficacy of an air purifier. If you have a large basement but buy a purifier suitable for a small space, that wouldn’t help a bit. You must measure the basement beforehand and choose a purifier capable of filtering the air of rooms of that particular size. Make sure that your purifier’s coverage capacity is greater than or equal to the size of the basement. Only then, you will be able to get fresh and clean air to breathe.

Maintenance

We are busy with so many tasks that it is hard to manage time for air purifier maintenance. So, look for a low maintenance unit that requires very less cleaning and the filter should last at least 6 months. Frequent filter replacement may bother you a lot as it is both annoying and costs money to buy new filters. 

Operational Modes

With the advancement of technology, air purifier manufacturers have introduced smart technologies like auto-shutoff, smart air quality measurement sensor, auto night mode, auto speed adjustment facility, filter replacement indicators, remote control, etc. Look for these extra features if you find them useful. You should also search for a simple and easy to use user panel so that it becomes easy to operate without too much technical difficulty. 

Noise Level

Different people expect different noise production from an air purifier. Some love to hear white noise whereas some prefer it ultra-quiet. But, the standard noise level of an air purifier for the basement is within 20-50 dB. You shouldn’t choose an air purifier that produces more than 50 decibels sound when operated at the highest speed.

Energy Efficiency

Check if your purifiers are certified by Energy Star. Energy Star examines and verifies the energy efficiency of different appliances. Their certification is trustworthy, so buy an air purifier with the Energy Star label stamped on it. This means the unit consumes low energy but works effectively. 

Design & Build Quality

As an air purifier is kept inside the room, it is important for you to enhance the beauty of the interior, not reduce it. Consider the design and dimensions of the air purifier and choose a portable unit so that you can move it around the room when needed. Focus on the aesthetic value of your air purifier. It can also be functional as a showpiece. 

Another important thing is the material and build quality. Choose purifiers made of quality materials like ABS. Inspect the unit before buying it. If it feels sturdy and long-lasting, then buy it. 

Cost

The efficiency of a product is measured against its price. If you get enough service as per the price, there’s nothing to complain about. That’s why you need to consider all the hidden costs before making a purchase. Learn about the price of replacement filters and how frequently you have to change them. This will help you understand the cost of having an air purifier for a long time. Also, look for the warranty policy. An extended warranty will help you if you receive a defective unit or if the unit doesn’t work well during the warranty period. 

If you look for these key features, we can assure you that you will find the best air purifier for basement as per your needs. To help you further, we listed our top nine picks here. You can choose any unit from this list. We are confident that they all are really good value for money.

 Buyers Guide and Additional Information

Now that you know all about our top picks, it’s time to get enlightened with other aspects of an air purifier for basement. The basement is often neglected by homeowners whereas they pay painstaking attention to improve the environment of other rooms. It becomes more necessary to employ an air purifier for the basement because a large number of people convert their basements into living rooms or offices. So, the quality of basement air is surely a concern. Now, the first question that may arise in your head is- “Are air purifiers good for the basement?” To know this answer we have to, at first, find out the reasons behind the poor air quality of a basement. 

What Are the Reasons Behind the Poor Air Quality in Basements?

You can’t blame a single thing for the poor basement air quality. A mixture of impurities like VOCs, mold, mildew, and a disturbing smell produced from stagnant airflow mainly cause the poor air quality in the basement. If the basement has carpets on it, it will definitely smell stinky due to the extra moisture. 

Moreover, the air in the basement doesn’t have enough space to create an air current, as a result, the environment becomes damp and smelly. Moreover, dust and other fine particles produced from stoves, chemical cleaners, fireplaces, paintings, and industrial pollution also contribute to making the air in the basement worse. 

Last but not the least, radon is a real nuisance for basements. If the underground soil of your basement is enriched with radioactive radon gas, this may pollute the basement as well. Radon gas enters the basement through the cracks in the wall. It is also found in water and various building materials. 

How to Get Clean Air in the Basement? 

There are many ways to improve the condition of your basement. The easiest way is to provide better air ventilation.  You can introduce more windows and doors if needed. This will ensure free airflow throughout the basement and, consequently, the air pollutants will not accumulate as before. 

Humidity is one of the culprits that cause bad air quality in the basement. A dehumidifier will be of great help in this regard. You can adjust and maintain a perfect level of humidity with it. We recommend you keep the humidity level within the range of 30-50% to get a comfortable environment inside the walls. 

If you have problems regarding molds and radon, you should consult experts who specialize in removing molds and radon. Molds are seriously tenacious and keep coming back if treated poorly. Before calling for expert help, you can use a test kit to detect the amount of radon in the soil around your basement, If the value is significant, go for professional help. 

The final and easiest way to improve the air inside your basement is to use a quality air purifier that is intended to filter basement air efficiently.
