Dust indoors is a serious health hazard and more serious that you may think. Household dust is the accumulation of tiny particles including of cloth fibers, paper, hair, pet dander, skin cells, dust mites, dirt, and similar micro airborne particles.

That is why Dust removal is so important, especially when you have allergies as a result of dust and other airborne particles. It is known that the young and the elderly are more sensitive to the hazards of dust, especially dust mites.

What to look for when deciding upon which best air purifier to buy for dust removal

1. Indoor Air Quality

This will depend on how severe the dust in a room is. And how bad you or your family members suffer from dust allergies and the dust from the outside environment such as pollen and other VOC’s. This is the primary reason why people buy air purifiers with true HEPA filters.
And how I personally start my journey in  finding the best air purifier for dust removal.
To relieve these allergies of the annoying and constant blocked nose because of dust mites and pollens.

2. Is the Air Purifier for Commercial or Domestic Space?

Certain purifiers are ideal for offices while others are appropriate for residential buildings.

3. Coverage area

How big is the area where the air needs to be filtered and the Quality of the air in that room?
Also how exposed its is to the major air pollutants such as smoke, dust, pollen and mold. And the amount of time required to clear the air in that area, this is indicated by the CADR scores of each air purifier.

True HEPA filters

HEPA stands for High Efficiency Particulate Air Filter, capable of filtering 99.97% of airborne particles as small as 0.3 microns in size. And should be an essential filter for air purification. HEPA filters do not remove gases or volatile organic compounds (VOCs)

Air ionizer (Ions)

Negative ions attach themselves to airborne allergens such as spores, pollen, mold some types of chemical vapors, bacteria and viruses and thereby help with neutralization or elimination of these allergens. This type of filtration is not essential for smoke filtration.

Active carbon filters

Carbon filters are used to filter out volatile organic compounds (VOC’s) smoke, cooking smells, odors and chemicals which is why it is very important for filtering any type of smoke firstly for the chemical compounds and that nasty odor, cigarettes, weed, and cigars leave behind.
You can wash and reuse your carbon filters

Ultraviolet (UV-C)

UV light has a serializing effect of short-wavelength light. Effective in killing mold spores pollen viruses and bacteria but only if exposed to the UV light for a long period of time enough to breakdown the cells by damaging the molecule DNA .  Commonly used for sterilization but not an essential feature for air purifiers.

Pre Mesh Filter

This pre filter is used to filter larger particles of dust and other particles in the air such as hair, to prolong the life span of the other filters.
An essential filter for air purifiers


PlasmaWave® creates positive and negative ions that combine with natural water vapor to form hydroxyls, which cleans the indoor air and safely breaks apart odors, allergens, chemical vapors, and other pollutants at the molecular level, without causing harmful ozone. This filtration system is exclusive to Winix air purifiers servers a great feature as a smoke air purifier.

Ozone generators (O3)

Ozone is a strong oxidant gas which can oxidize airborne pollutants. Effective for removing smoke odors, musty smells,toxic molds. Only for unoccupied spaces as it’s hazardous to breath.

Photocatalytic oxidation (PCO)

This technology commonly being used in the HVAC industry has the ability to completely oxidize and degrade organic contaminants such as Volatile Organic Compounds. Not an essential feature for air purifiers

Titanium dioxide (TiO2)

(TiO2) technology – nanoparticles of TiO2, together with calcium carbonate neutralize acidic gas particles when mixed into slightly porous paint. Not an purification method used air purifiers

How Do Dust Mites Affect the Air We Breathe?

Dust mites are tiny, insect-like, microscopic pests which gather on the surfaces of bedding, furniture or carpets. Feeding on our dead skin cells, they tend to thrive in humid and warm temperatures. They are the most common indoor allergens.

Signs that you are allergic to dust mites:

Dust mites allergy symptoms cause inflammation of nasal passages which causes:

  • Sneezing
  • Runny nose
  • Itchy, red or watery eyes
  • Nasal congestion
  • Itchy nose, mouth or throat
  • Postnasal drip
  • Cough
  • Facial pressure and pain
  • Swollen, blue-colored skin under your eyes
  • Frequent upward rubbing of the nose in children

In some cases, it may attribute to asthma causing symptoms such as:

  • Chest tightness or pain.
  • Difficulty in breathing
  • Wheezing or whistling whilst exhaling.
  • Sleeping difficulty due to coughing, wheezing and shortness of breath.

Therefore, when choosing an air purifier for dust mites it is important to know what to look out for and which are just vanity features.

Types of Airborne Particles


Most aerosols present in the atmosphere originate from suspended minerals in the soil. The comprise carbonates and a wide variety of oxides. A huge percentage of the aerosols include quartz, feldspar, micas and clay minerals. Their sizes range from less than 1 micrometer to 30 micrometers.

Metallic dust originates from the usage and processing of various metals (coming from the tiny waste remains from drilling, welding, and cutting metals). Prolonged exposure to metallic dust causes serious health issues such as Siderosis (caused by iron), Silicosis (caused by Silica) or Black Lung (caused by coal dust).

Organic and vegetable

Dust is also produced from plants and vegetables, kitchen ingredients, cotton, wool, flour, and pet litter.

Pet dander

Pet dander comprises tiny particles which birds and animals shed from their skins. They include fur and feathers. Dander contains a distinct protein which triggers allergic reactions whose symptoms include persistent coughing, Eczema, itchy and watery eyes. Some people display asthma-related symptoms.

Environmental scientists consider pet dander to be a type of dust. Nevertheless, the best air purifiers have HEPA filters which remove microscopic particles that are up to 0.3 microns large.

Industrial products and air pollution

Bulk chemicals from industries, as well as, the pesticides that we use contribute to another category of dust, namely, chemical dust.
Phthalates, flame-retardants, phenols, and fragrances are some of the most common sources of chemical dust.

Apart from causing common airborne diseases, these particles cause certain types of cancer. They act as breeding grounds for mold, which is equally harmful as dust. Moreover, the spores from molds contribute to the dust in the air.

Health Benefits of Air Purifiers

  • Air purifier cleanses the air in your room by getting rid of harmful and unhealthy particles such as dust, pollen, molds, smoke, urban pollution and certain airborne bacteria and viruses  larger than 0.3 microns.
  • Air purifiers trap the allergens released by the pets.
  • Air purifiers help to neutralize smoke and deodorize the air.
  • Air purifiers prevent seasonal allergens and airborne diseases from spreading.
  • Air purifiers keep our lungs and dwelling environment healthy.
  • Air purifiers rid your house of unpleasant odors.

Clean Air Delivery Rate scores and AHAM

The Clean Air Delivery System (CADR) is the performance metric figure assigned to the machine, based on independent tests undertaken by AHAM (Association of Home Appliance Manufacturers). They have been measuring the CADRs of Air Purifiers since the 1980s.
Some crucial aspect of the CADR scores are:

  • Cigarette Smoke
  • Dust
  • Pollen

It indicates the purifier’s capacity to remove particles in the range of 0.10 to 11 micron. It is expressed in terms of the volume of air.
Usually, 1008 cubic feet is the standard area for measuring CADR of a machine.
AHAM confers a mark on its certified household dust removal machine specifying the CADR scores. The higher the score, the faster the rate of purification. Moreover, it’s suggestive of the recommended room size for the purifier.
