5 Best Air Scrubbers For Mold Removal

Molds are one of the most common problems in both residential and commercial settings. In fact, more than 50% of American households suffer from mold issues. If not addressed, a mold infestation can lead to respiratory problems, allergies, and even permanent lung damage in the worst cases. While it’s not the only solution, the best air scrubber for mold will offer a big help.

If we are to compare air purifiers and air scrubbers, the latter is made with tougher filtration stages. Air filters only remove airborne particles while air scrubbers can clean both airborne particles and those clinging to surfaces.

Take note that air scrubbers are either dry or wet, which differs in the element they use for filtration. Nevertheless, both works wonder in eliminating contaminants.

Due to its powerful cleaning abilities, air scrubbers were initially used to clean harmful gasses and contaminants. Also, the first air scrubber was used to remove carbon dioxide from enclosed spaces. This same technology is also used in submarines.

Although air scrubbers are initially used for industrial purposes, you can now purchase them for home use as well. It’s now made into compact versions to suit the budget and needs of most homeowners.

Below, we reviewed five of the most reliable air scrubbers you can find in the market. See which one fits your budget and cleaning needs.

How to choose the best air scrubber for mold

If you’re new to air scrubbers, it can be tricky to pick the right one for your needs. To help you out, here are some of the points you should consider:

✔️Wet vs. dry

Air scrubbers are divided into two types: wet and dry. These two types mainly differ on the filtration method they use.

Wet air scrubbers use water or a wet substance to filter out contaminants. This is very efficient in filtering corrosive gasses and can be used at almost any temperature.

Moreover, nearly all particulates are eliminated by wet air scrubbers. However, this type is usually used in industrial settings and is quite a rarity for household settings. This is because disposal of the wet substance requires a special process.

Meanwhile, dry air scrubbers use physical filters to get rid of contaminants, including mold spores. While this is also able to eliminate gasses when paired with carbon filters, it’s not as intensive as wet types.

Nevertheless, dry air scrubbers don’t produce any sludge that requires disposal. Most units only require filter replacement or cleanup and they will be ready for use again. Aside from that, dry scrubbers are cheaper and can be purchased for home use.

✔️Portable vs. integrated

Air scrubbers can either be portable or integrated.

With integrated types, the scrubber is installed as part of your HVAC system. This means that the scrubber can work round-the-clock.

However, integrated scrubbers aren’t always practical for some reason. First, it’s costly and requires professional installation. Aside from that, maintenance of integrated air scrubbers will also add up to the ongoing expenses.

On the other hand, most households prefer portable air scrubbers. It can be moved around the house to use in rooms that require cleaning. Also, it’s easier to maintain and the upfront cost is much lower than integrated types. Above all, you can use it straight from the box and there’s no need for professional installation. 

If you’re looking for a budget-friendly air scrubber to remove molds in your home, portable types will not disappoint.

✔️Filtration type

Next, you have to consider the filtration system of the air scrubber you’re going to buy.

Personally, I recommend a unit equipped with High-Efficiency Particulate Air (HEPA) filter. This is effective in removing particulates as small as 0.3 microns. Medical-grade ones can trap up to 0.1 microns, ensuring that no mold spores get recirculated into the air.

You can also find air scrubbers fitted with carbon filters to neutralize bad odors and harmful gasses.

✔️Maximum airflow

Air scrubbers’ airflow is measured by CFM or cubic feet per minute. A unit with a higher airflow rate tends to be larger and more powerful in terms of cleaning.

Airflow rating in air scrubbers can be as low as 100 CFM to 20,000 CFM. For industrial use, 5,000 CFM is already powerful. And if you’re getting one for mold removal in your home, anywhere from 500 to 700 CFM would be an ideal choice.

✔️Speed

The speed of an air scrubber pertains to how many times it can cycle the air inside the room. Faster units are often used in bigger areas to ensure fast but reliable air cleaning.

Meanwhile, small rooms can make use of equally smaller air scrubbers. Take note that running a high-speed scrubber inside a small room is not just a waste of electricity, but also a source of unnecessary noise.

If you want to experience the best of both worlds, I recommend that you get an air scrubber with adjustable speed settings. This will give you better control based on the area where you’re planning to use the unit.

✔️Horsepower

The air scrubber’s horsepower directly affects its speed, airflow, and overall power to clean. For most home use, a unit with 1/3 HP to ½ HP is more than enough.

However, if you have a larger area to remove molds from, you can always upgrade to a higher horsepower rating. Still, you should remember that scrubbers with high horsepower also come with a bigger price tag.

✔️Coverage area

Aside from all the specs mentioned above, it’s also important to factor in the size of the place where you plan to use the unit. An air scrubber that’s too small or too big for your property will not serve its purpose well.

Most air scrubber manufacturers will indicate a maximum coverage area on their units. In general, you’d want an air scrubber with a maximum coverage area of 500 sq. ft. This would be more than enough for most homes suffering from molds.

Also, this coverage area is ideal after mold remediation or renovation projects. The good thing is that most of these air scrubbers have adjustable speeds to suit smaller areas.

✔️Price range

Lastly, always consider the price point of the air scrubber you’re going to buy. Cheap ones are convenient, but they don’t always last. Also, air scrubbers in the lower price range tend to have less power and minimal coverage area.

If your home is dealing with molds or has a history of molds, I recommend that you invest in a trusty unit. While the upfront cost is bigger, it will pay for itself over the years. Aside from that, scrubbers with a higher price tag also come with equally worthy warranty terms.
