How Indoor Air Purifiers Work


Air purifiers use a system of internal fans to pull the air in your home through a series of filters that remove harmful airborne particles like dust, pollen and bacteria. The air purifier then circulates the purified air back into the room. This process repeats itself several times an hour, keeping your environment healthy.

Why Do You Need an Air Purifier?

If you don’t think an air purifier is the right choice for your home; here are some reasons to reconsider:

  1. Air purifiers ensure your family is breathing clean air. The EPA estimates that indoor air is two to five times dirtier than outdoor air — and sometimes up to 100 times dirtier.
  2. You can stay healthy by using a good air purifier.
  3. Air purifiers. removes unpleasant scents. You enjoy cooking, but your weekly fish fry fills the home with the scent of, well, fish. Air purifiers not only clean the air, but also aid in the removal of unpleasant and burnt food aromas.
  4. Air purifiers can trap pet danders and other allergens. You may adore your pet, but he or she introduces pet dander, fur, and other allergies into your home’s air, not to mention the odors! Air purifiers work to prevent allergens from entering your home by trapping them.
  5. Air filters can neutralize smoke which causes an unpleasant odor.
  6. An air purifier can help catch smoke before it gets into your upholstery, whether it’s from a friend or relative who smokes or your fondness for a blazing fireplace making your home smell nasty.
  7. An air purifier traps dust before it has a chance to settle, decreasing build-up and reducing the amount of cleaning you have to do.
  8. Air purifiers can get rid of up to 99 percent of microorganisms in the air. Pollen, mold spores, and other microorganisms float around in the air, making your family sick.

Germs, allergens, pollen, smoke, dust, pet dander, and mold odors are all eliminated by the AZEUS air purifier. It’s also a fantastic option for people who suffer from allergies.

Installing the Azeus Air Purifier 

The AZEUS air purifier is extremely simple to install. Remove the front panel after removing it from the box to access the air filter.

Auto-Air Quality Sensor With Auto Mode

The air quality indicator on the AZEUS GL-FS32 Air Purifier measures real air quality and shows several color-coded air quality levels.

The red color, for example, indicates that the air quality in the room is low. The green color indicates that the air quality in the room is moderate. The air quality is good for human health if the indicator light color is blue.

When the indicator detects poor air quality in the room, the air purifier switches to a low-speed fan mode.

#2 Medify MA-40 H-13 Air Purifier


The Medify MA-40 air purifier delivers outstanding results in rooms up to 800 square feet. In a space this size, foul air is sucked in through the rear intake and clean air is expelled at a 2-ACH rate out the front outlet.

This implies that in one hour, it circulates all of the air in the room twice. The purifier also produces clean air at a rate of 330 cubic feet per minute, which is towards the top of the CADR scale.

H13 Filter of Medical Grade

Medify installed a massive three-in-one filter in the MA-40 to trap allergens, remove odors, and absorb VOCs without air escaping between the layers. An activated carbon layer, a pre-filtration layer, and a true-HEPA layer make up this filter.

Genuine HEPA filters are available in a variety of efficiency levels. This air purifier’s HEPA filter is made of medical-grade H13 media. As a result, it catches 99.97% of 0.3-micron particles as well as 99.95% of 0.1-micron particles, while delivering a level of cleanliness that few other purifiers can match.

Ionizer (Optional)

Additionally, the Medify MA-40 v2.0 comes with an ionizer. It emits charged particles that attach themselves to the dust in the air.

The ionizer can only assist in the removal of particles from the air, not odorous pollutants. It normally enhances particle CADR by about 8%. A little amount of ozone is produced as a consequence of ionizer filtering. The unit, on the other hand, is ozone-safe and CARB-approved.

In fact, if you have asthma or other breathing problems at home, you should not use this feature.

Level of Noise

The noise level of the air purifier is 46 decibels at the lowest fan speed and 66 dB at the highest fan speed. When compared to the air delivery rate, the noise level is slightly higher.

The minimal noise level is 46 dB, which isn’t exactly whisper-quiet. So, if you want to use it in sleep mode in the bedroom at night, keep it a bit away from the bed.

#6 SilverOnyx 5-in-1 Air Purifier for Mold, Allergies and Dust


In the realm of low-cost air purifiers, there are a plethora of microbrands that may only be recognized by residents of the United States. Hence, the SilverOnyx is one air purifier from a company like that, a company that uses its own name for its most popular air purification gadget rather than coming up with a fresh unique name. 

For instance, if you’re looking for a break from the large air purifier manufacturers, we’d like to introduce you to the SilverOnyx Review, which is for a fantastic 5-in-1 air purifier made by a Utah firm.

The 5-stage air purification procedure gives the SilverOnyx 5-in-1 air purifier its name. With these five air filtering technologies together, an air purifier can provide some of the cleanest, freshest air conceivable.

This product, in particular, generates a sterile environment by using Ultra Violet light to eradicate airborne germs—a feature that you won’t find on many other air purifiers of this size.

Types of Filters


Pre-filter – This filter is the very first layer of protection against airborne contaminants. It uses a micromesh material to catch big particles including dirt, hair, dust, and other contaminants.

H13 HEPA Filter – This is a good HEPA filter that comes in second place. The HEPA filtration system collects 99.99% of hazardous particles as small as 0.3 microns. Secondly, H14 is the next level up, and it’s 99.995 percent effective (or 0.045 percent )

Activated Carbon Filter: It can reduce volatile Organic Compounds (VOCs) and harmful gases such as formaldehyde and acetaldehyde. In addition, these poisonous compounds are frequently found in indoor air and can harm your health. As described in our tutorial on what an activated carbon filter accomplishes, this filter also lowers common household scents caused by cooking, pets, mold, and paints.

UltraViolet Light (UVL) – This method is used to kill bacteria, viruses, and mold spores. Thus, this creates a more hygienic atmosphere, keeping you healthier and less susceptible to illness.

Ionizer (Anion Generator) – This technology enhances the machine’s air-cleaning capabilities. It operates by releasing negatively charged ions into the air to aid in the collection of contaminants by the HEPA filter. (It can be activated as well as deactivated.)

What Makes a Good Air Purifier for Molds and Dust?

That’s an excellent question, as different air purifiers use different technology.

1. True HEPA filtration

This is a jargon term. Look for the phrase “true HEPA” on every filter. True HEPA is recommended, as well as a supplementary method of removing or eliminating mold.

2. Ultraviolet Light

Mold, germs, and viruses are known to be killed by UV-C (C spectrum) and other ultraviolet radiation.

The UV lamp is usually hidden inside or behind the HEPA filter, so its light isn’t visible (not that it would be harmful).

3. Ionization

First, a word of caution: most cheap ionizing air purifiers produce ozone, which should be avoided. Even the most expensive and highly rated air purifiers produce very little ozone.

At low levels, ozone is known to irritate breathing airways. It will harm tissue in the passageways at high levels. Asthmatics are particularly vulnerable to ozone. The Environmental Protection Agency has a page with useful connections.

Now let’s talk about safe ion air purifiers. Ozone is not produced or emitted by better ionizing air purifiers. Ensure that the air purifier’s literature clearly states that it is ozone-free.

4. CADR Rating

The CADR (Clean Air Delivery Rate) is a measurement of how well and quickly an air purifier operates. It shows how many cubic feet of air can be filtered in one minute for various contaminants like pollen, dust, and smoke. To ensure effectiveness, larger rooms will require higher CADR values.

5. Activated Carbon Filters 


They are rarely used by themselves, but are often used in combination with other filters. Activated carbon/charcoal filters help in absorbing odors and gases thereby neutralizing smoke, chemicals, and fumes.

Reacts with oxygen to open up millions of pores that are capable of trapping a large amount of gas and odor. It’s the perfect surface for connecting with chemical or vapour molecules because of this. 

For optimal performance, they must be replaced once they have been saturated.

Final Thoughts

Mold contamination in the home can result in both immediate and long-term health problems. Although air purifiers won’t totally eliminate the potentially dangerous fungus, they can help to lower the quantity of harmful spores in the air. When researching or remediating pollution issues, this might help provide peace of mind.

Mold can nearly always be found in the air we breathe, and as a result, it can bring a lot of illness. An air purifier can help limit exposure to certain allergens, which is especially essential for those who are allergic to them.

Finally, these best air purifiers for mold in this list captures a wide range of contaminants and allergens, making the indoor air cleaner and healthier.
