Types of Air Purifiers: Which Is the Best?

Low air quality is not just an outdoor problem but also an indoor issue. Although a space looks visibly clean, there are particles invisible to the naked eye. These pollutants can be hazardous to our health, especially if we just let them pile up and keep on circulating inside the room. An air purifier is your best defence to keep these allergens away.

Know more about the importance of having air purifiers, their types and which one is the best.

Benefits of Having an Air Purifier

Having an air purifier has a lot of advantages. Here are some of them.

1. Helps People With Medical Conditions

If there is someone in your family who has allergies or asthma, living in a house with airborne pollutants can be hard. This is because a lot of particles that are not visible to our eyes will be inhaled by these people, which can trigger their medical conditions. Having air purifiers in your space will solve this problem. They will capture these harmful allergens and ensure that the air in the room is clean.

2. Eliminates Odours

Air purifiers do not only capture dust or pollen. Some types are capable of removing unpleasant scents. This is advantageous to those who are sensitive to various odours like:

  • Food smells, such as spices and spoiled dishes
  • Garbage
  • Smoke, including the one emitted by cigarettes
  • Pet odour
  • Mustiness
  • Chemical scents like paint

3. Keeps Your House Free From Dust

When dust in the air is left untreated, it can pile up on your carpets, curtains and furniture, making your home look uninviting and hazardous to your health. Without the assistance of an air purifier, the constant presence of dust can cause you to clean more often.

Common Types of Air Purifiers

Air purifiers have evolved from using simple filters to having multiple features that enhance their performance.

Below are the common types of modern air purifiers:

1. HEPA Filter Air Purifiers

High-efficiency particulate air filter or HEPA is one of the most common types of air purifiers. Compared to other filters, a HEPA filter air purifier is much more effective in purifying a room because it has smaller openings. This makes it capable of trapping particles up to 0.3 microns in size with 99.97% efficiency. It can capture the following:

  • Dust
  • Dust mites
  • Pollen, fungi and mould spores
  • Pet dander
  • Bacteria and viruses.

2. Activated Carbon Air Purifiers

Air purifiers with carbon filters are useful if you want to remove unpleasant odours from an area. These are highly absorbent and use chemical bonding to capture chemical particles, gases, smoke and more.

3. UV Air Purifiers

This type of air purifier uses ultraviolet or UV to break down particles, rendering them unable to reproduce. It is capable of eliminating harmful pathogens, bacteria and viruses that may cause diseases in your family. It also prevents the growth of microorganisms that can create musty and other unpleasant odours.

4. Ionic Air Purifiers

One of the notable qualities of ionic air purifiers is that they can operate without a motor, making it extremely quiet while working. Instead of sucking particles towards it, these air purifiers release negative ions in the air, which bond with particles and increase their weight. Because they become heavy, they eventually fall out of the air.

5. Electrostatic Air Purifiers

Electrostatic air purifiers produce static electricity to trap airborne pollutants. They are like a magnet that makes use of positively and negatively charged particles to stick them into the filter.

6. Ozone

Although it is not recommended for indoor use, this type of air purifier is useful for industrial or non-occupant settings. They use corona discharge or UV discharge to gas ozone to separate oxygen molecules into two oxygen atoms and purify the air.

Things to Consider Before Buying an Air Purifier

Check for these factors first before purchasing an air purifier.

  • Is there someone who has allergies, weak immune system and sensitivity to smell? If yes, you should get a HEPA filter air purifier with high filtration rating or with UV light.
  • Make sure that the size of the air purifier can cover the size of the room.
  • Watch out for its level of energy consumption.
  • Do you want it to be portable or in just one place?
  • Check if its noise level is acceptable.

RENSAIR: The World's Best Air Purifier

If you are looking for an effective air purifier that can efficiently clean the air in your house or commercial space, RENSAIR HEPA filter air purifier is an excellent choice. It is a hospital-grade portable air purifier in Australia that uses advanced purification technology and UVC light to effectively eliminate particles and maintain good air quality.

• It Has Advanced Filter Technology

RENSAIR HEPA filter air purifier uses the four stages of air purification.

    • Utilises pre-filters to remove large particles.
    • Has a fan that creates high static air pressure and sends the pre-filtered air to the next filter.
    • Pollutants that managed to get through the first filtration process are caught by a HEPA H13 filter.
    • Microorganisms will not be able to circulate back into the air, a UVC lamp lights up the whole filtration area.

• It Kills Microorganisms

RENSAIR HEPA filter air purifier does not just filter out allergens but also kills them. This is due to the 18 w UVC lamp that emits radiation to effectively break down the DNA and RNA of pathogens that may cause diseases and odours. This adds a layer of security to ensure your family’s health.
