You might be wondering whether or not you really need an air purifier and what kind of difference it can make to your daily life. Here are just some advantages to having an air purifier in the home:

  • Safer and Healthier Air – Air purifiers aren’t just for those with breathing problems, allergies, or other health issues. Even if you’re in perfect health, you can still benefit from an air purifier. Why? Because they make air cleaner. Imagine breathing in better quality air each day, free of toxins, pollutants, and dust. It’s clear to see that this is a lot kinder to your body.
  • For Allergy Sufferers – Scientific studies have shown that those who suffer from allergies can also benefit from air purifiers. The best air purifiers like the Philips Air Purifier 1000 come with filters that can effectively remove dust, pollen, and pet particles from the air, creating a cleaner and safer atmosphere for all.
  • For Asthma Sufferers – Air purifiers can be potentially life-saving for those who have to deal with asthma. Many asthma triggers like dry skin cells and dust can build up in the air inside your home over time and trigger asthma attacks. An air purifier helps to remove these triggers and provide your body with cleaner, purer air.
  • Better Smelling Homes – Air purifiers work to reduce carbon dioxide levels, remove cancer-causing pollutants from the air, and create a safer space for all. Many of the top models also feature filters that combat unpleasant odors, making your home smell fresher and cleaner each day.
  • A More Positive Mood – Having an air purifier can even help to lower your stress levels and make you feel more positive each day! Studies have shown that those who breathe in fresher and cleaner air each day are less stressed than those living in polluted conditions. By breathing in clean air, your levels of cortisol start to lower, putting you in a more relaxed state.

Features to consider when choosing an air purifier

Before you start shopping for your air purifier, it’s important to think about various features and factors. This will help you make the right choice, selecting the perfect air purifier to match with your home and needs. First, you’ll want to consider your overall budget and set out a maximum price you’re willing to pay.

This will help narrow down your overall selection and make it easier to choose an air purifier. Next, you need to think about a variety of factors like the number of cleaning stages, the types of filters inside your air purifier, and the working area it can provide in order to choose a device that gives you the performance you desire.

Number of cleaning stages

The whole purpose of an air purifier is to clean the air and provide a safer, cleaner, healthier environment in your home or place of work. The number of cleaning stages of your chosen purifier is therefore a very important factor to think about. Put simply, purifiers with more cleaning stages tend to be better overall.

This is because devices like the Airthereal Day Dawning ADH80, which features an extraordinary 7-stage cleaning process, are able to filter out greater numbers of pollutants from the air. They suck in polluted and unclean air, taking out all of the different allergens, dirt, dust, and other undesirable particles.

Machines with more cleaning stages are stronger and more effective overall. They also offer a greater variety of uses, being useful for allergy sufferers, asthma sufferers, those with other health conditions, and those who just want to enjoy fresher, cleaner, better smelling air in their bedrooms, living rooms, and other spaces.

Type of filters used

Another key feature to consider when shopping for an air purifier is the kind of filters contained within. These days, there are many different filter types, and they all have different jobs and purposes. Some of them are good at getting rid of allergens, while others work to destroy odors. Here are some brief explanations of common filter types to look out for:

  • HEPA Filters – HEPA filters are among the most common filters you find in air purifiers. They’re also known as air cleaners and work to trap particles from the air on a piece of foam, fiberglass, cotton, or another materials. HEPA filters usually come with a MERV rating; the higher the rating, the better the filter. Some air purifiers come with a range of different HEPA filters for more thorough purification, like the Alen BreatheSmart FIT50.
  • Ionizers – Ionizers make use of particle charges to attract dirt particles and other undesirable elements from the air and capture them, causing them to stick to surfaces rather than floating around in the air and putting people at risk.
  • Activated Carbon Filters – These are some of the best filters for trapping odors and actually making the air around the air purifier smell better and cleaner. The porous carbon used in these kinds of filters works to trap in gases and unpleasant smells, as well as large particles like pet dander. Be sure to look for an air purifier with a carbon filter if you want it to tackle bad smells, like the Winix HR900 or Hathaspace Smart True HEPA Air Purifier.
  • UV Lights – UV, or ultraviolet, light filters are used to actually make your home a safer place to be. They can kill bacteria and even viruses. This helps to make everyone safer in the home, ridding your rooms of microbes and reducing the spread of illnesses. A UV light also helps to keep the air purifier itself clean and bacteria-free, preventing the growth of mold as well.
  • Pre-Filter – A pre-filter, as the name indicates, acts as the first layer of filtration before the rest of the filters start to work. They’re designed to trap and collect quite large particles like big bits of dust, pollen, hair, and fibers. This kind of filter can be seen on the Medify MA-40 and GermGuardian AC4100.

Working area

This is another very important factor to think about when buying an air purifier. Working area tells us how much space the air purifier can help to clean up. It’s basically an indication of how strong the unit is. Stronger air purifiers, like the Alen BreatheSmart FIT50 and Rabbit Air MinusA2 are able to clean larger spaces of several hundred square feet, some even are the whole-house air purifiers, while weaker or smaller models are designed to handle smaller spaces.

Bigger is better when it comes to working area, but it isn’t always necessary to get a super powerful air purifier designed for spaces of 800 square feet if you’re only going to be using it in a little apartment or single room of your house. If you plan to use the air purifier in a smaller space, you can save money on a simpler model like the AeraMax 100 Air Purifier, for example.

Before choosing an air purifier, think about where you’re going to be using it. Ask yourself what kind of room or space you want to purify and how big it is. Then use that information to choose a model that matches your needs. There’s no use in buying a purifier that is overpowered for your environment or not strong enough to tackle the size of your room.

Clean Air Delivery Rate (CADR)

Clean air delivery rate is a measurement that essentially tells us how quickly an air purifier is able to function. On a scientific level, CADR denotes how many cubic feet of air a purifier can handle per minute. When we talk about CADR, we usually look at three key readings: one for smoke, one for pollen, and one for dust.

Some units are able to remove something like dust more quickly than pollen, for example, or vice versa. Either way, the faster the rate, the better the air purifier. Having a purifier that can function quickly is very important, especially if you aren’t able to leave it running non-stop and want to use it in little bursts.

Fan speeds

Another interesting aspect of air purifiers to consider is the fan speeds. Many of the best rated air purifier models will feature a range of different fan speeds. More options in this category help to make the machine more versatile, giving you more options in terms of how you set it up and how you use it each day.

A lot of air purifiers tend to have around 3 fan speeds as standard. However, there are models out there that offer even greater functionality. The IQAir HealthPro Plus Air Purifier, for example, has six different fan speeds and various modes and settings to give the user a greater level of control.

Noise level

If you’re thinking about investing in an air purifier, one of the key things to note is that they can be noisy. Some low quality air purifiers can get very loud, producing a constant humming or whirring sound as they operate. Lowering the fan speed can help with this, but the noise can still be distracting, especially if you use the air purifier in the bedroom and try to sleep while it’s in operation.

Fortunately, the noise level of air purifiers can vary a lot, depending on the model you buy. There are some super silent air purifiers out there, like the Philips Air Purifier 1000 or Airthereal Day Dawning ADH80. These models, among others, are designed with comfort and convenience in mind, operating at low dB ratings to provide a more satisfying experience for the user.

Before buying your air purifier, think about how much the sound might bother you. Some people don’t mind hearing a fan-like sound, and some even like to sleep with fans to help them drift off more easily or drown out other ambient sounds. Some people, however, are very easily bothered by these kinds of noises. If you want a quiet machine, be sure to shop around for one with a low dB rating.


Another thing to think about is the actual size and weight of your air purifier. Many people make the mistake of thinking that all air purifiers are quite large, heavy, and bulky. However, this isn’t always the case. In the modern era, there are many high-tech air purifiers that actually feature very slim, compact, lightweight designs.

The smaller models are sometimes less powerful, but this isn’t always true. You can get quite small models like the Coway AP-1512HH that are still super powerful and fully-featured. These smaller options are often more convenient as you can mount them or install them more easily without disturbing the aesthetic of your home.

One last factor you should think about when buying an air purifier is the warranty. These devices are designed to last for years without any issues, but they can sometimes break down or encounter technical issues. It’s always nice to know that the manufacturer has got you covered in cases where problems arise. Be sure to check the warranty on any air purifier before you buy and choose models with long warranties for total peace of mind.
