These tips and evaluation criteria will help you in finding the most appropriate product for purchase.

1. Type of Filters

The are different technologies that create different types of air purifiers. These varieties vary in performance and cost. Let’s take a comprehensive look:

– HEPA Filters

HEPA is the most common type and most popular also. It is most efficient as the technology can remove up to 99.97% of particles.

You can expect it to catch contaminants in 0.3 microns size and the mold substances are of similar size. This means, it is very easy for HEPA filters to eat mold and mildew contaminants.

The drawback of these filters is that mold can grow on its surface, so you will be required to clean it frequently.

– PECO (Photo Electrochemical Oxidation)

Light activated catalytic reaction is used by these machines to kill the contaminants that passes through the system.

The plus side is that you don’t have to worry about growth of mold in the filter with this product.

– UVGI (Ultraviolet Germicidal Irradiation)

This technology sterilize air in the room and kill any harmful bacteria or particles in the air.

No doubt that this is an efficient technology, but it creates intense UV rays inside the room that will cause more problems than mold.

– Carbon Filter

The most popular use of a carbon filter is to remove airborne chemicals from the environment. It is done by trapping the gases on carbon filter.

This particular type is not very effective in removing the mold spores as it is not meant for this purpose.

– Ionizing Air Purifiers

It follows the basic mechanism of ionizing as the particles will start to stick to the close-by surface due to the electric charge.

The performance is decent yet they are not considered as a suitable choice to make because they generate ozone which will cause a lot of damage.

Our Tips: Since you have seen all the plus and minus of each type, we recommend you to buy the best HEPA air purifiers for mold.

It is highly effective and cause no damage for the environment.

2. Speed Settings

Speed settings are responsible for the air circulation rate. We will explain it with an example. In humid weather, mold grows faster than other seasons.

Therefore, an air purifier with different speed settings will be effective in such case as you can set speed to the highest.

At the same time, during summer season, the ventilation is ensured by opening windows and you don’t have to run the filter on same speed. You can keep it to the minimum.

Some of the best products also comes with 5 speed settings which make them extremely diligent. One of the most recommended products with various speed settings is the SilverOnyx 8541832765 air purifier.

3. Coverage Area

Your pursuit for the best air purifier for mold and mildew will also largely depend on the coverage area it is capable of handling.

If you have a small room where the purifier has to be installed then a product with coverage area of around 150 – 170 square feet will be suitable.

However, there are some models that go as high as 900 square feet in coverage area, proving to be suitable for larger rooms.

If you are aiming of a large room then consider RabbitAir SPA-780A air purifier as it comes with 815 square feet coverage area.

4. Noise

In search for an air purifier to get rid of indoor pollution, we often make a mistake of trading one pollution type to another.

This means that to get rid of air pollution, we sometimes end up buying a product that causes a lot of noise pollution.

A noisy air purifier will disturb your peace and sleep. That is why, you should be very careful while selecting these products, especially by checking its noise level.

The noise is referenced in “dB” unit. A product with smaller dB value will be less noisy than the one with high dB value.

Most air purifiers that comes with versatile speed ranges have noise levels like 21 – 45 dB. This means that the lowest speed will cause 21 dB of noise whereas the largest speed will take it up the notch to 45 dB.

You should make sure to purchase a model that causes less noise, even on its full-power performance.

5. Warranty

While not all products come with warranty but it is essential that you make a wise purchase and pick a model that gives you some peace of mind.

The companies that are absolutely sure of their creation always offer good warranty and you should always prefer the purchase from such brands.
