What to know about air purifiers

What to know about air purifiers

Air quality. It’s something we’re all thinking about more and more, especially since the pandemic focused our attention on how diseases spread through the air. Now, everything from pollution to hay fever regularly hits the headlines at various times of year.

It sounds crazy, but air quality indoors can actually be up to three and a half times worse than it is outdoors – even in a city. We have the wonders of modern house insulation to thank for that, and it’s a legit health concern.

That’s why in this article, we’re going to be delving into how effective air purifiers really are at ‘cleaning’ the air in our homes. Can they really create better air for people and pets to breathe in?

What does an air purifier do?

Let’s start with the basics. Air purifiers filter harmful particles out of the air, whether that’s…

● Dust 🧹
● Smoke 🔥
● Pollen 🌸
● Spores 🍄
● Any other nasties affecting the air quality in our homes 🦠

They generally work their magic by combining a high-speed fan with a filter, sucking in air, trapping pesky particles in said filter and then chucking ‘clean’ air out. They typically get to work very quickly, in most cases clearing a room in minutes.

Brief but relevant tangent: On the filter front, you might have heard of a ‘HEPA’ filter, which stands for ‘high-efficiency particulate absorbing’ (catchy).

These high-quality air filters are great for people with allergies. But they’re not necessarily the best option depending on what you want your air purifier for.

On the lookout for an air purifier that’s up to the job of getting rid of grim smells? A charcoal filter will be much more effective.

Do air purifiers actually clean the air and improve air quality?

You might not be able to see the dirt in the air, but it’s there. And ‘cleaning’ the air is effectively what an air purifier is doing when it draws that ‘dirty’ air into the unit.

Whether it’s dirt, dust, pathogens or volatile organic compounds (VOCs), the air purifier traps the unclean stuff in the filter inside. These particles are held inside to keep them out of harm’s way, keeping the air in your home lovely and clean.

Do air purifiers remove smells?

So far, so great: air purifiers do indeed clean the air, and therefore do improve air quality. However, the bad news is that there’s one thing they don’t remove from the air. And that’s horrid smells. ☹️

Getting sciency for a minute, the reason for that is…

🤓 Smells aren’t particles. They’re molecules the nervous system recognises as smells.
🤓 That’s thanks to the interaction between chemicals – those in the nervous system and the chemical molecules our noses pick up as smells.
🤓 HEPA filters won’t help. They’re the most effective for filtering particles, but not molecules – so they can’t get rid of smells.

That’s what makes our Smell Away® a bit different. Because along with acting as an air purifier, it uses a best-in-class activated carbon filter to trap smells and keep them trapped. Plus a hush-hush ingredient we can’t mention. 🤫

Do air purifiers remove smells?

If you’re at the point when you’re considering buying one, you might be wondering whether air purifiers are really as effective as the descriptions make them sound.

The short answer is yes – air purifiers definitely do work, and will make a fast and noticeable difference to your indoor air quality.

A slightly longer answer would be that if you’re looking for an air purifier that will also banish stubborn smells (whether it’s pet odours, cooking smells, cigarette smoke or worse 😬), you’ll need more than a basic air cleaner purifier, even with a HEPA filter.

To do that, you’ll need to go for an air filtration system that uses an activated carbon filter to trap these odours.

Our Smell Away® is just such a system. It combines smell busting, dust removing, air cleaning and air purification into one small yet mighty machine. Get yours today and start enjoying better air quality – all while making horrid smells history.
