Part One: Did you Know that your Air Purifier is Lying to You?

To begin with, let me just say that this isn’t one of those click-baiting headlines that brings you here and sells you stuff – this is the real deal!

Believe it or not, your air purifier is actually lying to you!

There are two aspects or features where marketing lingo is misguiding you – the consumer – and they are:

  • Air Quality Indicator
  • Clean Air Delivery Rate

In part one, we will tell you how companies are making fools out of you by twisting the truth and presenting it in a way that baffles consumers.

Find the Air Quality Indicator on your Purifier

You know, those fancy little lights that show different colours or numbers to indicate you have “clean air”?

It’s usually “red” for dirty air and as you keep the purifier running, slowly turns to “green” – that’s the one we’re talking about.

A lot of people look for the air quality monitoring feature as well, before picking their air purifier.

In fact, we have been told by numerous people to get one on our air purifier as well.

However, before we get into whether we need one on Cair Air Purifiers or not, lets’ just take a moment to see whether there’s really any merit in choosing air purifiers based on their indicator.

Is the Indicator Worth anything?

If you are interested in knowing whether your air purifier has an air-quality indicator or not, then there’s one more question you need to ask.

What does the indicator detect?

This one question can have many answers, and the key lies in the answer you get:

  • Does it detect PM2.5 levels?
  • Or is it meant for PM0.1 levels?
  • Does it detect all Volatile Organic Compounds?
  • Or do they not inform you at all about what the indicator detects?

There are different pollutants in air and there are different devices/techniques to measure their quantity in the air you are breathing.

Most air purifiers cannot detect anything beyond PM2.5!

So when they are telling you that your air purifier has cleaned the air in your room, what they are  essentially saying is that most of the PM2.5 particles have been captured by your air purifier.

The mistake is where they begin to tell you that your room’s air quality is good or great, indicated by their own unique green light or special read-out.

The problem is, your air purifier is not measuring the VOC content in air – it cannot – and so when it tells you that the air is clean, you are being made a fool!

The air is not clean because it has no way of knowing whether the air is clean or not.

Anyone who tells you that their air purifier’s indicator is showing you the levels of VOCs as well, is lying to your face!

Why? Because there are different tests for different kinds of VOCs.

Benzene levels in air cannot be determined based on a test designed to detect Formaldehyde.

Similarly, NO2 levels are not indicated by a test for Hydrogen Cyanide.

You can only Measure PM2.5, not VOCs

So here’s the truth then – your air purifier, if it is capable, can only measure PM2.5 levels in your home and (if the provision exists) one or two other kinds of VOCs like Sulphur Dioxide or Nitrogen Oxide.

However, it cannot tell you the overall quality of air in your home – which is PM2.5 + Chemicals & toxin levels (or VOC levels).

Please understand that this does not mean that your air purifier is not cleaning up those elements from air.

If it has an HEPA filter, it is probably cleaning up PM2.5 pollutants and if it has an activated charcoal filter, it is also likely cleaning up VOCs.

However, the indicator is not indicating actual levels of pollutants in the room.

Basing your buying decision on whether your air purifier has an indicator or not is like basing your doctor’s choice based on whether they have a thermometer or not.

Sure, they can check your body temperature, but you cannot check your blood pressure with a thermometer – you need a BP monitoring machine!

In fact, the medical world is the perfect analogy because you have different devices for different tests.

The chemical and toxin world of air purification is much like that – there are different techniques and devices required to measure different chemicals and toxins, and your air purifier cannot possible house every single one of them.

So, if you are buying an air purifier, don’t pay too much attention on the air-quality indicators – they are nothing but a marketing gimmick to make you trust the device more than you should.

There are more marketing gimmicks out there, but this is one that can actually lull you into a false sense of security, and you may not realise that you are still living in conditions far worse than what you are made to believe.

In Part Two of the article, we will look at another aspect of air purifiers that you might require clarification on – Clean Air Deliver Rate or CADR.
