The air quality in our homes has never been more important than now, when current events around the world have left many of us wondering when we will next have some respite from acrid air.
Whether you already have one of the best air purifiers, or are trying to get by without one, keeping your home’s air clean is vital to your health, and the well-being of your loved ones – whether that be filtering out wildfire smoke, dust, or extreme levels of pollen.
Here, HVAC experts explain how to improve air quality indoors both with and without an air purifier.
How to improve air quality indoors
Although many of us have questioned if air purifiers are worth it in recent years, it is becoming more and more apparent that these handy devices will be as essential to our homes as our refrigerators in the years to come – so investing is certainly the smart option.
But, if you are stuck without one and need to clean the air quickly, there are some makeshift alternatives you can try at home.
1. Keep windows and doors closed
Whether using an air purifier or not, it is vital to keep your windows and doors closed to protect your home from contaminated outside air, explains the HVAC experts at Friedrich Air Conditioning.
In cases of extreme outdoor air pollution, it is best to also seal your doors and windows using sealing strips, such as these from Amazon, to keep your home's air as pure as possible.
2. Recycle air with an AC unit
While you may not think to run your AC when air quality is bad, turning fresh air intake off on your air conditioner and setting it to recycle is a great way to slightly improve the air quality in your home without a dedicated air purifier, suggests Joshua Bartlett, home improvement expert at I’ll Just Fix It Myself. For the best effect, you need to make sure your AC filters are completely clean and regularly changed.
‘Doing this ensures that allergens, dust, and other particles won't be able to drift around your house as freely,’ Josh explains. ‘It's simple and cheap, too.
‘When replacing filters, double-check that the new ones you buy are a good match for your machine,’ he adds.

3. Buy an air purifier – and use it correctly
Of course, the best way to purify the air in your home is to buy an air purifier, but it is important to use them correctly if you want to truly benefit from them, reminds Christopher Coleman, of HVAC specialist DH Life Labs.
‘When picking an air purifier, invest in a device that is capable of removing fine particles, such as those produced by wildfires. These are usually devices with HVAC or gas filters.
‘It should then ideally be placed in the room where you spend most of your time, such as the bedroom or living room, and positioned in a way that allows air to circulate freely into and out of the device – so avoid placing it up against furniture or walls.’

4. Use air purifying plants
If the air quality is not too dire where you live, then you could rely on some air-cleaning indoor plants to help keep minor pollutants at bay, suggests Michael Golubev, air quality expert and CEO of Mold Busters.
‘I suggest opting for spider plants, English ivy, snake plants, and peace lilies, as these are all known to improve indoor air quality by absorbing toxins,’ he recommends. ‘It is important to note these will not be as effective as a purifier or HVAC system, however, so use them in conjunction with a device in times of bad air quality.’
5. Set up a safe room, for extreme conditions
Although an extreme solution, it could be wise to set up a temporary ‘clean room’ somewhere in your home to stay safe from severe air pollution, such as in instances of wildfires or dust storms, advises HVAC specialist, Christopher Coleman.
‘This room should have as few windows and doors as possible, preferably situated towards the center of your home, and be set up with essentials so you can comfortably stay in there for a few hours, learning how to keep a room cool without windows, and adding an air purifier too if you can.’

Doctors around the world have agreed that air purifiers, when used correctly, are a good idea for any home – especially those with a HVAC filter.
