OK ...

Right, with those reviews in place, you should be able to see at a glance which of these air purifiers would make the neatest fit in your home.

As usual, we’ll finish up with some handy hints to make your life easier starting with a quick explanation of dust and why it’s so crucial to purify the air in your home…

What is Dust and Why Should You Care?

As there’s no way around dust in your home, you need to take air purification into account as a means of dealing with it.

What is dust, though?

Well, it’s nothing more than a collection of various particles. How dust is composed depends largely on the make-up of your home. Do you have pets? What type of food is being cooked? Does anyone in the household smoke? All these factors dictate dust composition.

UP to 60% of all dust is created outside. As the particles from soil, plants, and animals enter the air, they make their way into your home uninvited.

Climate and outdoor air conditions are also central in terms of the quantity of dust that gets into your home. Clearly, if you live somewhere with an arid, dusty climate, you’ll be more prone to a dusty house.

The cells of skin and hair degrade with a little dust made out of the waste. Pet hair and dander along with the by-products from cooking and household chemicals all contribute toward the dust problem, too.

Varying significantly in size, you need multi-stage filtration to deal confidently with all types of dust and debris.

Dust mites are larger than you might imagine at 100 to 200 microns.

What, then, should you look out for when you’re on the buying trail?

Which Air Purifier Works Best For Dust Removal?

When your main motivator is removing dust, you need a HEPA-rated filter. A high- efficiency particulate air filter is tested under rigorous lab conditions to remove all particles down to 0.3 microns.

Dust particles enter your home then travel around until they have a surface to settle on. An air purifier prevents this from happening for the most part. So, not only will you be breathing cleaner air, you’ll cut down on cleaning and dusting, too!

To be clear, what you’re looking for with an air purifier is to drastically reduce the amount of dust polluting your indoor air. You’re never going to eliminate this completely. As long as you’re reasonable about your expectations, you’ll end up delighted with your purchase.

If you have pets or smokers in the home, it’s well worth focusing on filtration that includes a carbon-activated component. This will help to neutralize all those unpleasant smells.

Finally, you should consider whether or not you’re happy with the concept of negative ionizers. If you’re not sure what these are, come back next week when we double down on these in more detail.

A Final Word

We trust you’re now fully placed to find the best air purifier the easy way. Stick with any of the units we review today and you’ll end up breathing more easily, especially if you have allergies or asthma.
