Buyer’s Guide:

Air Purifiers For the Basement

Why Is Basement Air of Poor Quality?

In most cases, basements are smaller cramped spaces inside the home that is used for storage. In turn, moisture levels are kept elevated, because of poor ventilation and the carpets that impair air quality.

Basement spaces are also given very little care and maintenance efforts. Before you know it, that downstairs room you have at home had already accumulated years’ worth of mold, mildew, and other airborne irritants that are actually very hazardous to your health.

This is where your air purifier comes in. Whether or not you spend a lot of time in the basement, it would be necessary to keep the air fresh and clean and not put your respiratory health at risk.

Guidelines for Purchasing the Right Basement Air Filtration System

Depending on the state of your finances, an air purifier can turn out to be more of a luxury item. With that in consideration, here are some guidelines you can adhere to before making that purchase.

  • Make Sure It Can Handle the Size of Your Basement

    Basement sizes vary from one house to another, and will depend on the manner of which storage is done. But you will need an air purifier that will be able to work with the space you have available.

    There are purifier brands that can cover up to 700 sq. ft. of space, and these are the ones you would want at your disposal. It may not cover the entire room, but make sure that it can at least purify a great majority of the surrounding air.

  • Quality Filter that can Remove Mold Effectively

    The purifier’s filtration system is another aspect to take a good look at. Most brands on this list are capable to eradicate airborne particles through its multiple stages of purification. A good product will usually have a True HEPA filter and activated carbon filter to work against allergens and odors.

  • The ability to Rid the Air of as Many Pollutants as Possible

    Similar to the previous item, the HEPA filter is usually the component of an air purifier that can eliminate up to 99% of airborne particles that can go as small as 0.3 microns. A product with a built in ionizer is also adept at eradicating both allergens and odors, solving two problems with one solution.

  • Look for an Energy-Efficient Model

    As previously mentioned, you would not want to pile on more expenses with a new device such as an air purifier. So if you intend to spend quite a chunk on the machine itself, at the very least, make sure of its energy efficiency.

    You will know if a brand falls under this category if it bears an Energy Star rating, which means that it can run for hours while not inflicting that much damage on your monthly electricity expenses.

Frequently Asked Questions

Why should I use an air purifier in my basement?

Unmaintained rooms like the basement are the common breeding grounds for harmful airborne bacteria like molds, or allergens like dust. Especially if you are a usual victim of these irritants, you will need an air purifier and not compromise your health.

What types of pollutants should the air purification system be able to remove?

The usual pollutants that an air purifier should be able to remove are dust, pollen, pet dander, and mold spores, which are common fixtures in any home. But there are machines that can go as far as eradicating the DNA of the bacteria through their built-in ionizers and UV-C technology. This prevents the spread of any of these pollutants right from the get-go.

If I place an air purifier in the basement, can I turn this area into an extra bedroom or living room?

Having an air purifier in the basement will definitely make it a more livable space in your home. But at the same time, you will have to consider the space you will be working with, given that most basements are compact and cramped.

If you can creatively and efficiently set things up to maximize the space, you can turn your basement, or any room in the house into an instant living area.

Final Thoughts

The basement may not be the most inhabited room in your home, but it does not mean that it is exempt from air purification. When it comes to finding out that would be most suitable, you would want to go for the most effective one that would help you make the most out of your spendings.

That being said, the best choice to make from this list would be the Alen BreatheSmart FLEX. It checks out in all categories such as aesthetics, functionality, coverage area, and efficiency. Best of all, you are supported for life by its manufacturers.
