What is an air purifier?

An air purifier is an appliance that is very helpful for those that suffer from allergiesasthmachemical sensitivity and other respiratory related symptoms as it removes certain airborne pollutants from the air and improves the indoor air quality.

What are the different types of filters?

There are three main types of air filters in your air purifier:

  • HEPA Filters:  High Efficiency Particulate Air (HEPA) filters remove 99.97% of particles that are 0.3 microns and larger from the air. This makes HEPA filters ideal for removing small particles, dust mite residue, and pollen from your air.
  • Carbon Filters:Using activated carbon, these filters remove odours and chemicals from your indoor air. These include cigarette smoke, fireplace fumes, formaldehyde, volatile organic compounds (paint fumes, carpet glues, new building materials, etc.), pet odours, and kitchen odours.
  • Pre-Filters: These help extend the time between filter cleanings or changes as well as maintain the air purifier’s functionality and efficiency by trapping large particles before they reach the main filters of the air purifier.

How much space does an air purifier cover?

Air purifiers are designed to fit a variety of spaces, from large to small. Make sure you look at the square meters of the room it will be primarily used in. The details of the coverage size are in all of our product descriptions.

Where should I put my air purifier?

Most air purifiers are designed to clean only one room, so it’s best to place an air purifier in the room you spend most of your time. This is often considered to be the bedroom, but you might prefer to put it in the living area, or in the children’s play area. Wherever you want clean air, we can provide it – you can even get purifiers for your vehicles.

What are the best air purifiers for allergy- and asthma-sufferers?

All our purifiers are designed to take out all allergens and pollens to help asthma sufferers.

What air purifiers are best for pet dander?

All our purifiers are designed to take out all pet dander and odour.

How much maintenance is required for the air filters?

The first filter change should occur 6 months after first acquiring your purifier, and every subsequent change need only occur every 12 months, or when your purifier replacement filter indicator tells you to. The initial change is as a result of cleaning out the initial pollutants that are sitting around in your home.

What happens if the air filters are not changed when the indicator light comes on?

With dirty air filters your air purifier may not be cleaning thoroughly, resulting in poor air quality and increased risk for respiratory illness symptoms. To ensure that your air purifier is functioning at its best change the filters when indicated.

What does CADR stand for?

CADR stands for Clean Air Delivery Rate, which is the volume of air clean by the purifier per hour. The higher the CADR number, the faster the unit filters air.

What does CFM stand for?

CFM stands for cubic feet per minute.

To find your ideal CFM, calculate the total volume of your space (length x width x height in cubic feet) and divide this number by your desired ACH. Below is a sample equation:


CFM  =

18 ft x 24 ft x 8 ft
5 (air exchanges)
CFM = 3456
CFM = 691.2

What is a micron?

Short for micrometer, a micron is one millionth of a meter. Microns are used to measure airborne particle sizes. Because particles are so small we cannot see them, but they are still there, and while we can’t see the difference an air purifier makes, we can certainly feel it.

Do all air purifiers clean the same type of pollutants from the air?

All of our air purifiers possess all the filters listed below so that we target the full range of pollutants with all purifiers.
HEPA Filters: Fot thorough particle filtration. If you want to address odours and chemicals, Carbon Filters: For odours, airborne germs and chemicals.
Ultraviolet lights

Are air purifiers loud?

The noise of an air purifier is dependent on fan level at which you are purifying. The most noise will be produced on the highest setting of any purifier, but even at that rate the noise is minimal. Keep mind, however, that noise is subjective so noise that some may tolerate may not be tolerated by others.
All of the models also possess a night mode which functions at a lower fan rate to minimise noise at bed time.

How long should I run my air purifier?

We recommend that for the best results you should run your purifier continuously. They are designed to be run non-stop. If noise is a factor, you can choose to run the purifier at higher rates while you’re out of the home, then turn the fan down to a quieter level when you return.
When the air purifier is turned off, air pollution returns to its pre-treatment state.

What happens when I turn my purifier off?

When the air purifier is turned off, air pollution returns to its pre-treatment state.

Is it expensive to use an air purifier?

The two factors to consider are both the cost of the replacement filters and the cost of electricity. A simple calculation can be done to work out the cost of an air purifier for you:

(Power Consumption of the nit (watt) x Rate of Electricity ($/kWh) x Hours of operation) + 1 (or 2) filters/year.

How do I know if my air purifier is providing me with the promised benefits?

Within a few days you will notice a difference in the purity of your room – it will no longer feel heavy. You will experience fewer symptoms of allergy and be able to breathe with less difficulty. For visual proof just take out your filter to view the filth that has been removed from your air.

Which air purifier is best for me?

There is no air quality difference between any of our purifiers. The only difference is in size and amount of air purified per hour.

To evaluate which purifier is best for the size of your room please check the square-metre and cubic-metre specifications in the descriptions of our products.

Can I open my windows while the air purifier is running?

Yes it is perfectly acceptable to mix fresh air in while the purifier is running. It is actually the indoor air that is more pollutant than the outdoor air (in New Zealand).

How easy is it to mount your air purifier?

Depending on the type of wall it should not take more than 30 minutes from the point of unpacking the purifier to plugging it in after fully securing it to the wall.
Tools required: Philips screw driver and cordless drill for concrete or gib board to put in a gib board (which is supplied).
