The indoor air quality in our homes can be negatively impacted by many different pollutants. Dust, smoke, mould, dust mites, pollens and chemical off-gassing from furniture and carpeting are all contributors to the indoor air pollution problem. Allergens like pollen cause reactions if their presence is too high so it is important to maintain good ventilation to help mitigate this. Other organic pollutants like moulds can also contribute to poor wellbeing if exposure is prolonged.

In addition to these organic pollutants, we also have airborne viruses and bacteria that travel quickly through air-conditioned environments. Tobacco smoke is another source of indoor air pollution that has been linked with numerous health concerns.

Bushfires pose a huge risk as their smoke can travel for long distances and contain particles smaller than 1 micron that can enter our homes easily through ventilation systems. All of these issues can lead to worsening wellbeing conditions if corrective action isn’t taken which makes it clear why improving the quality of our indoor air is so important.

The smoke generated by bushfires and hazard reduction burns is having devastating impacts on health, presenting serious risks of short-term and long-term health effects. These risks are particularly severe for pregnant women and children. Bushfire smoke has high concentrations of particles in the air, ranging from large to ultra-fine. For the latter, they can travel hundreds of kilometres away from their origin and remain airborne for prolonged periods of time. They pose the biggest threat when it comes to inhaling the smoke.

How Air Purifiers Help

Air purifiers are a specialised device used to filter and clean indoor air. A fan is used to generate a flow of air through filters that are designed to trap different size particles, including ­bushfire smoke pollutants, allergens which can cause hay fever, and even the airborne transmission of the COVID-19 virus in certain circumstances. In recent years we have come to see how important air purifiers can be to households who live in areas where pollution or disease is more likely or predominant.

An air purifier can be incredibly useful to reduce exposure to airborne pollutants in the home. It can help remove common household allergens such as dust, pollen and mould as well as smoke from back-burning or bushfires. Smoke from a bushfire is very irritating and even damaging.

Air purifiers can improve the overall atmosphere of your home by removing bad odours caused by cooking or pets.

This indicates that they have the ability to filter airborne viruses, bacteria, and small particles called “particular matter.”

By keeping indoor pollution at bay, you can ensure that everyone in your family breathes clean air.

Therefore, an air purifier can easily improve indoor air quality without having to leave the comfort of your own home.

When looking for a device to help with air purification, experts recommend researching and finding a device that features a Carbon and HEPA filter.

HEPA Filter

The HEPA filter is a High Efficiency Particulate Air filter that works by pushing air through a fine mesh, allowing it to trap small particles such as pollen, dust mites, and tobacco smoke – finding one with this feature is especially beneficial for Australians who have are exposed to bushfire smoke. Additionally, it’s important for the purifier to have a fan to spread the fresh air around the room – some better models may already have this feature, but owners can add additional airflow by using an external pedestal fan. This helps ensure that not only is the clean air being circulated effectively and evenly throughout the room or house.

HEPA filters have been proven to be effective in filtering airborne viruses, bacteria, and particulate matter from bushfire or hazard reduction burn smoke.

This ensures an extremely high level of filtration for indoor pollutants, which helps ensure optimal benefits. Not all purifiers have this feature so double check product specifications before buying one. Overall, if you’re looking to improve your indoor air quality quickly and effectively, investing in an air purifier with a HEPA filter is essential for optimal benefits.

Carbon Filters

Carbon filters are essential tools in modern living, and can be used to improve indoor air quality by removing unwanted odours. The filter works by passing the contaminated air into a chamber filled with activated carbon. This porous material consists of tiny particles that quickly absorb and capture organic molecules, leaving the air fresh for breathing. Carbon filters have become increasingly prominent in households with pets or multiple smokers, as they help reduce levels of smoke, smog and odours from the environment.

In addition to filtering potentially hazardous compounds found in the home or workplace, activated carbon filters also come in handy for everyday use. For example, when your kids play with the toaster dials and accidentally burn breakfast, you can reduce the smell by quickly bringing out an activated carbon filter nearby. It is amongst one of the most efficient ways available to fight against indoor odours, which allows you to keep up with your daily routines. Furthermore, this type of filter helps improve your home comfort and get rid of contaminating smells quickly without having to turn on fans for hours at a time— you can quickly swap out the carbon filter!

Air purifiers are beneficial for your home or office by removing pollutants from the air, but do they dry out the air? The short answer is no. Air purifiers are designed to capture airborne pollutants rather than remove humidity from the air. Their filters work to capture particles such as dust, pet dander, germs and pollen floating in the air. An internal fan then circulates clean air throughout the room, though this has nothing to do with humidity control whatsoever. Therefore, it is unlikely that using an air purifier alone will not change the humidity of the environment whether it’s higher or lower.

Aside from not causing any changes to your desired temperature and humidity levels, running an air purifier can make for a comfortable living space overall due to its ability to help rid you of those airborne allergens and pathogens. It’s important to know what type of filter your system uses as well so that you know how often you need to change it out for optimal performance. With regular filter changes as needed, combined with other methods like having a dehumidifier on hand if necessary, when needed, you can enjoy optimal comfort in your living space!
