An air purifier is an essential piece of equipment in many homes, primarily in ones where those who suffer from allergies, asthma, and other respiratory issues live.
They are there to filter the air in the room they are placed in, removing harmful allergens and pollutants that are in the air. What comes out is a cleaner, far more breathable air that can benefit the house of those who would otherwise be suffering.
This guide takes a good look at some top air purifier reviews, so that you can discover the best air purifier for the home you live in. With a range of models, sizes, and brands, you are sure to find something that suits you here.
It doesn't matter what your budget is, or whether you want a model that is portable or freestanding, we are sure to have the perfect air purifier for you.
Best Air Purifier for the Home
Who Needs an Air Purifier?
It’s nice to have cleaner air inside, especially since it can become stale and still quite quickly. This is especially true in areas where air pollution is quite high. However, it is also very beneficial to those who have allergies and asthma.
The reason for this is that the air purifiers are able to remove pollutants and allergens from the air effectively through the filtration system. The important thing here is that you get an air purifier that is good at its job. Those with a lower rating and test score will take a lot longer to clean the air, and if you are suffering from allergies this isn’t something you have time for.
Types of Air Purifier
There are several different types of air purifier available on the market. Here is a quick rundown of the most commonly found forms:
Desk. These are small and compact, as well as ideal for small rooms that don’t need a massive amount of purification. Effective for their size.
Tower. These are tall and cylindrical like your kitchen bin. They are often powerful enough to work in large open-plan spaces.
Portable (Large). These are about the size of a carry-on suitcase, and they are also one of the most powerful. Certainly the most effective at cleaning the air in large living spaces, and come in varying wattages.
Oscillating. These can be large or small, and the rotate as they clean the air.
Fans. Dyson is the only company that actually has a model like this. They are quite expensive, but many customers have also found them highly effective.
Key Features to Look for
Here are some of the key features that you should be looking out for when you select an air purifier for your home:
Automatic mode and air sensors. Essentially, as soon as the air purifier detects pollutants in the air it will get to work. This is something you can adjust manually, and it is ideal to have if you live in a busy or polluted area.
Timer. If your model doesn’t have the sensors, you can use a timer to ensure that it switches on or off after a certain period of time. It means you can come home to clean air, but also saves you money on your bill.
Night Mode. This setting allows you to have a quieter cleaning experience (often with dimmed lights) so that you can sleep while it works.
Smart tech. Some models can be paired with a smartphone and controlled using an app. It can give you information about the air quality in your home as well, which is pretty handy to have with you.
How Much are Air Purifiers to Buy and Run?
The cost to buy an air purifier is one that spans a range of price brackets. There are some that are less than £100, and others that climb up to nearly £1000. The best threshold to be in for a good and reliable model is around £200. You’ll usually get a great machine for this price, although there are some great bargains out there.
The cost of running an air purifier does vary, but here are some average figures for each size machine based on leaving it to run for 12 hours a day:
Large and powerful: £72 per year.
Medium: £40 per year.
Small: £26 per year.
HEPA Filter: Do You Need One?
Ideally, your air purifier should have a HEPA filter. It is used for catching allergens and pollutants so that when the air is purified you get clean air being pushed back into the home. Many machines come with replaceable HEPA filters, but there are some with washable forms as well.
How long does a HEPA Filter Last?
The lifespan of a HEPA filter is dictated by how often you use your machine, and so it should be replaced every three to six months. You should still check it monthly to ensure that it is not too dirty and keep on top of the health of your machine.
HEPA vs Super HEPA - Whats the difference?
This is something that surprisingly few people know about. The HEPA filter is one that we are all familiar with, and the fact that it can collect particles as small as 0.03 microns is very impressive. This also translates to 99.7% of allergens being successfully collected. It’s an incredible filter, but it is also not the best HEPA out there.
The Super HEPA takes things further. It is able to capture particles as small as 0.01 microns, and this actually includes viruses. It is the ultimate form of air cleaning and allergy protection.
It’s not massively easy to find Super HEPA filters at the moment, but increased demand means that they are becoming more widespread.
Air Purifiers and COVID-19
A common question at the moment is whether or not air purifiers are able to help prevent COVID19. We actually have a detailed piece on the topic that will take you through the science, as well as whether or not an air purifier is beneficial for combatting the virus.
Are Air Purifiers Quiet?
There are quiet and noisy air purifiers, but one thing to remember is that the setting you have your machine on at night can dictate how loud it will be. If you keep it on the lowest setting at night, many air purifiers will be completely silent, or at least quiet enough that it doesn’t disturb your sleep.
Our guide is the perfect way to discover which models are going to leave you sleeping easy, and which might run the risk of leaving you staring at the ceiling.
