Difference Between Mold and Mildew

Before jumping into the product Reviews, let’s take a short look at mold and mildew difference.

Mildew refers to a specific type of mold, while a mold is a fungus that can grow in different shapes and colors like black and green. Mold can penetrate below the surface and affected materials. On the other hand, mildew can grow on a flat surface and cannot penetrate through the material.

Furthermore, Mildew is found on the home’s organic materials like paper, texture, and fabric. Mildew requires a specific environmental condition to grow; it cannot succeed without a moist environment. A particular humidity level from 62 to 93 percent with a temperature between 25oC to 31oC is ideal for growing mildew.

Important Note: “Never mix bleach with ammonia or other cleaning products; it may be the cause of toxic fumes and harmful gasses.”

Furthermore, due to this technology, when pollutants and particles pass HEPA Silent electrostatic barrier, they are electrified. After this, these particles are attracted by the filter like a magnet. Its filtration system consists of two parts, which are:

Smoke Filter: This filter is likely a combination of a right HEPA filter and an Activated carbon filter. Activated carbon in this air purifier is made of copper oxide and magnesium dioxide, which is very useful for any gases, VOCs, and smells.

Particle Filter: This particle filter can remove the fine particles of dust, mold, mold spores, allergens, and others up to 99% as small as 0.1 microns. You can choose between the particle filter and smoke stop filter according to your choice.


As its name shows a classic design air purifier that has a steel body with excellent finishing. With its steel body, it is a durable air purifier. Its height is 21 inches and width is 17 inches, while weight is 22 Lbs. Its air intake grill is in the back; this grill is quite bigger to ensure maximum airflow.

Furthermore, the air outlet is at the top of the air purifier. At the top of the air purifier, there is also an LED Display. You can monitor the air purifier performance with this display.

If you want to purchase an air purifier with smart features and powerful performance, you should go for Blueair’s classic 205 air purifier. It could be a good air purifier for mold and mildew. It is a onetime investment because of its durability.

But it would help if you keep in mind that this air purifier has a high price while comparing it with other brands in the same specifications. Another thing that is unbelievable in this brand is that it has no built-in smart sensor.

In our opinion, an air purifier’s primary function is air filtration, and in this model air filtration system is excellent. If you can afford a price, then what are you thinking? Go and grab this.

Common FAQs of Mold and Mildew Air Purifiers

Which kind of filtration technology is best for mold and mildew air purifier?

Different kinds of filtration systems are installed in an air purifier to improve your indoor air quality. Every filter has a specific function; before selecting the best air purifier for mold and mildew, take a look at a different type of filters; which one is the best to get rid of mold and mildew?

best air purifier for mold and mildew 2021

HEPA Filter: (High-Efficiency Particulate Air) is the primary type of filter used in air purifiers. HEPA filters are made with fiber; these filters can catch particles up to 0.3 microns and clean the air up to 99.97%. HEPA filters are the best to capture mold spores from the perspective. HEPA filters catch most mold spores because most mold spores are large than 0.3 microns.

But there is some problem with HEPA filters when they capture mold spores; these spores start growing on the fiber surfaces and discharge more spores. HEPA filters are not washable, and they are changed after a specific time; that’s why mold spores start growing to form the filter surface.

PECO: Photo Electrochemical Oxidation filters are used to destroy indoor air pollutants despite trapping them through filters. Each filter is coated with a nanocatalyst that meditates an oxidation reaction and kills contaminants in the air. PECO technology is also best to destroy the mold spores when passing through the device.

PCO: Photocatalytic Oxidation is an upgrade version of PECO technology; it can break organic molecules like mold spores and VOCs. Some people consider this technology inefficient, while some claim that PCO breaks mold spores and eliminates viruses and bacteria. In our opinion, this technology is not suitable for asthmatic patients because it can produce ozone, which is a harmful gas inside indoor areas.

UVGI: (Ultraviolet germicidal irradiation) or ultraviolet rays are used to kill microorganisms, mold, bacteria, fungi, and viruses for decades. This technology is now used in the best air purifiers for mold and mildew to improve indoor air quality.

Carbon Filters: Different kinds of filters can be capture mold spores, but how to deal with mold’s musty odor? For this purpose, activated carbon filtration technology is best to remove gasses like volatile organic compounds, odor from mold spores, and also absorb other gasses. These filters may be washable or not; see instructions before washing.

Ionizers or Ozone Generators: Ionizing is a process in which electrically charged particles spread through the air, and when they contact pollutants, they laid down these pollutants to the surface. They cannot kill or eliminate mold spores, and they have not any impact on mold spores. At the same time, ozone is also harmful in indoor areas, even at low exposure.

Do Air Purifiers Help With Mold?

The right answer is yes! Best air purifier for mold and mildew containing HEPA and activated carbon filter helps eliminate mold spores and eliminate the musty odor of mold. Most mold spores are large than 0.3 microns in size and easily catch through HEPA filters from the air.

Mold spores are very tiny and lightweight; they can float in the air hourly and easily trapped through the air purifier. The best air purifier for mold and mildew cannot remove mold from the surface once it starts growing. For this purpose, you need a powerful HEPA vacuum cleaner to extract mold from soft surfaces.

Some peoples claim that Stachybotrys chartarum is dangerous for human health, but this statement does not have any scientific evidence. As discussed above, different people act differently under the same condition, or some people may be more sensitive to mold to affect more.

These molds need a warm and high level of humidity to grow. Many black molds are toxic and can be harmful to human health. These molds discharge spores; they thrive rapidly and colonies with other spores.
