Must Known Factors for the Best Air Purifier for Basement

Before rushing out and buying just an air purifier for the basement without considering essential factors will not give you expected results. Here are a few aspects you need to look out for in order to ensure high air quality.

1.    Activated Carbon Filters

Many air purifier filters come with the feature of dual filtration system out of which one is the activated carbon filter.

These are the filters that are helpful to get rid of any pungent smell. The activated carbon filter is the filtration method that traps the odor molecules.

It is a must-have feature in the air purifier for the basement because it is the only feature that reduces the cellar odor.

It is done through a chemical process called adsorption that removes the volatile organic compounds and removes the musty smell making the air breathable.

2.    Coverage area

This is an important factor that you should go through before getting your air purifier. You must know the area that the unit covers and would it be sufficient for the need.

However, the range and capacity varies from device to device.

First thing is knowing the area of your basement, whether it is very large or too small or medium. Therefore, in order to see the difference in air quality, it is mandatory to make sure that the basement air purifier you buy covers your space.

You can measure the cellar and basement in square feet.

These measurements will help in determining if the device stands on your requirement. Reading, reviews, and device specifications can help you reach a decision.

3.    High-Efficiency Particulate Air (HEPA) filters

Make sure that your air purifier must have a true HEPA Filter. HEPA filters are essential in the best air purifiers for mold in the basement.

The HEPA filters have the ability to capture particles around 99.97 % but particles that are as small as 0.3 microns can escape only. These particles may include mold spores, allergens, dust, smoke, pet dander, and thousands of other particles roaming in the air.

While selecting the device, keep a check if it features HEPA filters or not as they are essential elements in maintaining air quality.

4.    Modes of Operation

You should select the easy-to-use air purifier with various modes like some models that feature auto modes, particle sensors, and quality indicators.

Having different cleaning modes will make the operation easy because you do not have to monitor the fan speed constantly.

Secondly, make sure the device must have an auto-shut off feature. This is important in the means of safety. You just need to set the time and it will be turned off automatically.

5.    UV light

It is also a must-have feature in the best air purifier for the basement. It maintains the air quality by killing the curbs and microbes.

UV light utilizes the beam of light in order to destroy the DNA of microbes. It is completely safe for humans. However, it is instilled in the device, so you do need to worry about the light in the room.

There are units that solely possess UV filters. If you are going to get this air purifier then make sure it is capable of capturing the smell too.

6.    Noise Production

Usually, the air purifiers produce the noise along with vibration when working. It is not a big deal for many.

When you are choosing the air purifier for the basement, it is a critical factor to consider because the close place makes the sound echo and increases the level to some extent.

The noise for the units are measured in dB (decibel).The favorable level is 30 decibels for the air purifier.

Whether you use the basement as a recreational room or a bedroom, do not forget to consider the noise production of the device.

We suggest you go for the device that produces noise no more than 60 decibels at normal speed.

7.    Quality and Durability

Basement air purifiers are likely all day; having the solid quality material prevents the trapped particles from escaping.

Despite its strong durability, high-quality devices do not discharge harmful byproducts like ozone.

 You can also check the warranty of the device as there is always the possibility of the device breaking down anytime. High-quality and durable devices are more likely to give a longer run.

8.    High Efficiency

With air, monthly billing can also irritate you because air purifiers for the basement run throughout the day.

The more energy a device consumes, the more monthly bills you will have to pay. High energy-efficient devices will help you save a lot.

Before getting a hand on the device, check the energy efficiency rating and if it is Energy Star Rated.
