Filters And Stages

What is the best air purifier for dust allergies? When choosing the best home air filtration system, you should first identify which type of filter you need. The filter within the air purifier plays a vital role in the treatment and management of air pollutants.

There are several different filters available, all with various functions. For example, asthma and allergy sufferers should look for the best air purifier for dust removal and mould particles, whilst pet owners might be looking to remove pet dander and odours.

To help you find the best air purifiers Australia, we have summarised the different types of filters and functions below:

Pre Filter

Many of the best brand air purifier come with a pre filter. This is a great option to consider having because it is designed specifically to filter out larger particles such as hair, dust balls etc.

The best room air filter is usually equipped with a pre filter to ensure the purifier doesn’t get frequently clogged.

  • Designed to filter out larger particles
  • Ensures filter is not constantly obstructed

HEPA Filter

HEPA stands for High Efficiency Particulate Air, and this filter is highly beneficial because it  collects the tiniest particles. It is one of the best permanent filter air purifier solutions and guarantees to remove 99.97% of pollutants.

If you or someone in your household is an asthma or allergy sufferer, the HEPA filtration will make a huge difference to overall health because it collects all the pollen, mould spores, bacteria, pet dander etc, leaving you with clean air to breathe. It is also the best air purifier for smoke 2021, as the filter can capture fine ash and soot specks.

You will have to be prepared to change the filter regularly which may be a bit costly. However, when you invest in the best HEPA filter for allergies, you are guaranteed that the filter will remove even the smallest particles that will immensely improve the air quality.

  • Highly beneficial for asthma and allergy sufferers
  • Guaranteed to remove 99.97% of pollutants
  • You will have to change the filter regularly, which may be a bit costly

Charcoal / Carbon Filter

The best carbon filter air purifier consists of tiny absorbent pores which trap gases, fumes, stenches and odours. It is also useful for removing air pollution and smoke. The best charcoal air purifier is relatively affordable and cheap to replace.

  • Removes odours and smells and will help your room smell fresh
  • Not effective for removing allergens and other bacteria
  • Affordable and easy to replace

Ozone Filter

In terms of the best air purifier for kitchen smells, ozone filters work great for removing odours and stenches. However, the gas produced by these types of filters can be harmful to humans if the space is not well ventilated. Be sure to follow instructions correctly.

  • Will eliminate odours
  • Doesn’t remove chemicals and allergens
  • Can be harmful to health

Ionic Filter

The best ionic air purifier works quite uniquely. Using a small electric field, this air cleaning technology releases a cloud of charged positive and negative ions that clasp airborne impurities. The contaminants then fall to the ground or any close surface.

  • This filter is very quiet and doesn’t need any maintenance
  • The pollutants remain on the floor, which requires frequent cleaning
  • Ionic Machines may emit ozone as a side effect that can be harmful to health

Ultraviolet (UV)

Unlike the other filters above, the Ultra Violet (UV) technology within the best budget air purifier options actually kills bacteria, viruses and germs rather than collecting them. It will rarely need replacement and will provide you with a germ free and sterile environment.

Make sure you note that this best air purifier for pets and dust cannot be bought as a single device – it works in conjunction and as an add on to the filters above.

  • Kills bacteria, viruses and germs
  • Works as an add on to other filters

Sensor And Timer

When searching for the best rated home air purifiers, consider ones with air sensors to monitor and display the level of pollution within the room.

Some of the best air purifier home models can automatically adjust the settings to improve air quality. This is highly useful if you live in the city near busy roads as the pollution levels will be higher during the day compared to nights.

A simple timer function within the best air humidifier and purifier can be convenient, so you can set the machine to run at specific times during the day. You will also be able to save energy consumption during the night with this feature.

Size, Weight And Portability

The best purifier for home can be pretty heavy, so if you plan to move it to a different room check the weight of the machine before buying. Carrying handles and caster wheels can make moving the purifier much easier.

best air purifier

Room Size

One of the worst mistakes you can make when choosing the best room air cleaner is not checking the purifier’s capacity or not adequately measuring your room size, making the unit ineffective.

To ensure this disaster doesn’t occur, look out for the square footage rating on the best air purifiers for home use and then compare it to the size of the room you need it for. Keep in mind – purchasing an air purifier that is too large for your room will give you a hefty electricity bill, so try to stick to the correct measurements. The best air purifier for bedroom should have a smaller capacity than whole house units.

Noise Level

To effectively clear out pollutants within the household or office, the best air cleaner for home will need to run most of the day. If you choose a noisy purifier, you will have to essentially listen to it the whole day. Particularly if you are a light sleeper or sensitive to noise, try to opt for an inexpensive air purifier that won’t disturb your sleep.

Another option is to pick the best in home air purifier, which is larger in capacity than your room size, so you can run it on a lower speed setting and avoid loud noise.

Fan Speed

Consider getting an air purifier with various fan speed settings when selecting the best air purifier on the market. This will give you greater control over the unit to adjust the fan according to your necessities.

If you end up buying the best brand for air purifier but it doesn’t have a range of speeds or good air circulation, the air around the purifier will likely keep getting cleaned, still leaving pollutants at the outskirts of the room. Take note – a cheap air purifier might become noisy on higher speed settings.

Extra Features And Functionalities

When comparing different models of the best air purifier and humidifier, added features and functions might influence your decision as to which purifier is best suited to your needs. Some features may seem like an added expense that aren’t so useful in the long run. I have included a brief summary to help you choose wisely!

Operation Modes – Choosing the best rated air purifier for allergies with different operation modes can increase its versatility and will save you the cost of buying different machines. Common modes including cooling, humidifying, heating etc.

PM2.5 Readout – PM2.5 is also known as “fine particulate matter” and refers to molecules in the air that are less than 2.5 microns in width. This readout measures real-time air quality with a value from 0 to 500.

Smart Technology – If you don’t mind paying extra for added convenience, many air purifiers come with WiFi connectivity, wireless control via an app and smart scheduling so everything can be done at the press of a button.

Remote Control – This will give you the comfort of controlling the machine from a distance.
