7 Common Misconceptions about Air Purifiers

Blog / Uncategorized / 7 Common Misconceptions about Air Purifiers
Back to Articles

Over the years we’ve been asked many questions about air purifiers. These appliances employ one or more filtration or sterilisation methods to make the air in your room cleaner, healthier and fresher.

These ‘miracle machines’ can work wonders but many people don’t realise what exactly they are for, how they can help with a range of problems, and their unique benefits. Here’s a run-down of the things that people most commonly get wrong about air cleaning machines…

1. They’re only for people with serious allergic conditions

An air purifier can benefit everyone, even people without any allergies or sensitivities. All air purifiers will remove a certain level of allergens, odours and impurities from the air, leaving your environment generally healthier and cleaner. For example, using an air purifier is a healthier alternative to filling the atmosphere with synthetic air fresheners, which can emit VOCs. Rather than simply smelling clean, the air in your room is clean. Depending on the model, some have sophisticated capabilities in removing airborne bacteria and viruses, which can help you and your family to stay well all year round. Some models can mop up airborne chemicals and VOCs, which can trigger headaches even in those who are not considered chemically sensitive.

All in all, an air purifier benefits everyone – not just allergy sufferers.

2. One is enough for the whole home

Unlike dehumidifiers, air purifiers are room-specific. It’s very important to choose an air purifier that meets your room size requirements, too. We base ours on 3 air changes per hour as we feel that offers a measure of thorough air cleaning, although manufacturer’s recommendations may vary.  (If you need help with this, you can contact us).

3. You’ll never need to clean again

Many people are surprised that their rooms still gather dust even after installing an air purifier. It’s important to remember that most of the airborne impurities affecting your indoor air quality, including the most hazardous ones, are invisible. The air purifier is quietly tackling these in the background whilst you go about your day to day business.

Although air purifiers do trap a substantial amount of dust and debris in the filter, they are in no way a substitute for a proper cleaning regime! In fact, some air purifiers with inbuilt ionisers can even make the area around the unit seem dustier. This is because the ions attach to the allergens to create heavier particles, which can sometimes drop to the floor.

4. They’re noisy

Early models of air purifiers used to get a bad rep due to their noise levels. Many units require a powerful fan to suck the air into the unit, which of course creates a little noise pollution.

However, nowadays there’s no need to put up with a noisy unit. Many are completely silent (such as these Airfree air sterilisers). Those which still make use of a fan have been carefully engineered to create as little noise as possible. For example, the Blueair units include an extremely powerful fan yet the built-in HEPASilent technology allows the units to run at as low as 32dB on the lowest setting. If low noise levels is a priority for you, contact our team and we’ll be happy to advise on the best units for your requirements.

5. They’re no good unless they have a HEPA filter

Many people think that the only air purifiers worth exploring are those with a HEPA filter. Although HEPA filtration is a great addition to any unit (especially the certified True HEPA filters), it is not the ‘be all and end all’ of great air quality.

Some units simply employ different technology to get similar, if not better, filtration results than HEPA. For example, the Meaco AirVax uses a patented SEFF filter which is able to capture even smaller particles than a standard HEPA filter. The Airfree units actually sterilise the air using a patented thermodynamic sterilising system, meaning that 99.99% of organic particles that pass through the ceramic core are destroyed.

6. An air purifier will cure all of my allergies

An air purifier is by no means a ‘magic bullet’ to provide answers to all of your allergy problems. They can be very helpful but are not a cure! A holistic approach is needed in order to keep allergy symptoms properly managed. That said, an air purifier can make a big difference to your comfort levels and relieve symptoms by taking away a large percentage of airborne allergens.

7. They are expensive to maintain

Many people worry about the long-term cost of using an air purifier at home, from running costs to replacing expensive filters. However, nowadays this needn’t be as much of a concern.

Modern air purifiers put energy efficiency as one of their highest priorities. Take a look at the power usage of some of our units and you may just be impressed!

Looking for the Energy Star certification assures you that the air purifier is 40% more energy-efficient than standard units – this is a good standard to look for if you are mindful of your energy usage and want to be kind to the environment.

Filter replacement costs are another common concern. However, you can actually find air purifiers that are completely ‘maintenance-free’ and require no filter replacement at all – the Airfree air sterilisers are an excellent example of this. The units which do require filter replacement are more reasonably priced than you might expect– you can find details of which replacement filters are needed and when on our product pages.x
