Air Purifiers


You might have a lot of questions regarding air purifiers vs air humidifiers, air purifier benefits for homes and other indoor spaces, benefits, side effects, and filter details. This blog is carefully curated to answer all your questions so you can make a purchase and let your air be fresh and clean with a little investment. So, stick with us till the end.

What is an Air Purifier?

Air Purifier is an electronic device which works as an effective air cleaner. This device takes in indoor air and filters it to breathe out fresh and clean air for a healthy and clean environment. It traps the pollutants, allergens, dust particles, and other compounds from the air in the filter

How Does Air Purifier Work?

Air purifiers work straightforwardly. The two main components of room purifiers are the fan and HEPA Filter. The fan integrated inside the purifier attracts air from the environment and pushes it to a filter which traps all the negative compounds from the air. The fan then pushes the fresh and clean air out into the room.

Air Purifiers usually have HEPA (High-Efficiency Particulate Air) filters which absorb all the small compounds like viruses, bacteria, dust, allergens, and pollutants from the air. Many of the purifiers also come with washable or replaceable filters that make them more convenient and useful for consumers. Moreover, you can also find UV light or carbon filters for more safety, cleanliness, and freshness.

What does an Air Purifier Remove from Air?

Air purifiers are effective in removing the following compounds and particles from the environment:

  • Small Particles of dust
  • Pollen or Allergens
  • Smoke particles
  • Dust mites
  • Animal Fur
  • Mould
  • Bacteria and Viruses
  • Odour

Air Purifiers vs Air Humidifiers

Air Purifiers

Both of these devices help keep your environment fresh and healthy. However, they do not perform the same function and one should not be mistaken for the other.

An air purifier is used to clean the air by removing all the micropollutants from the environment. It has a fan and a filter which takes in air and breathes it out after cleaning it. It helps remove bacteria and viruses from around us and aids in asthma and allergies.

On the other hand, air humidifier serves a different purpose. It does not clean the air but adds water to the environment in the form of steam. Humidifier adds moisture to the air and helps in cold, flu, skin dryness, etc.

A lot of brands offer air purifier and humidifier combinations that serve both purposes in one.

Benefits of Air Purifier

Air Purifiers

By installing a purifier indoors, you can gain the following benefits:

  • Reduces symptoms of asthma
  • Removes harmful gases and chemicals from the air
  • Filters air from viruses, bacteria, and allergens.
  • Aids in better sleep
  • Controls mould growth
  • Eliminates unpleasant odour
  • Traps dust for a cleaner environment
  • Reduce airborne diseases

Potential Side Effects

Although purifiers for homes are beneficial they require extra care. If not properly maintained and cared for, they may bring the following potential side effects:

  • Lower-quality HEPA filters may not get rid of all the pollutants
  • Blocked filters can blow out contaminants like mould, bacteria, and dust back into the environment.
  • Dry air can cause sore throat, sinus, irritation, and other side effects.
  • Ionizing air purifiers can cause serious health issues related to the lungs and headaches.


Having an air purifier can bring a lot of healthy benefits to your home and add to the longevity of your family member’s lives. So, it would help if you looked for the best choices in the market to invest in the durable and effective one. It may seem like a luxury but in the worsening air quality, an air purifier is a need for all households, offices, and indoors. Therefore, get one and let the air surrounding you pass through a purifying filter before it gets to your lungs.
