Best Air Purifiers for Home Use 2020

Thanks for taking the time to read our reviews on the best air purifiers for home use. We think the very first question to ask is do you really need an air purifier in your home?

Each and every year millions of Americans think about purchasing an air purifier for their home or to use in their business. For most people this consideration happens simply because they are just wanting to breathe clean air.

Did you know that Americans spend over $500 million buying air purifiers each year? That is a huge amount of money. Here we look at the best air purifiers for home use.

Why the Sudden Rise in Air Purifier Purchases?

Most people would consider that they keep their home clean and tidy. It can be hurtful, even offensive to then suggest that all of this hard work still results in a home that may have air pollution.

In simple terms how can your home be considered as dirty and yet you spend time cleaning it every day?

A key failure with many modern homes is that they are built to tight specifications. This is done mainly to meet pretty tight energy efficient specifications and a lot more than existed 20 years ago.

So although you may now be doing really well at conserving energy, the size of homes are smaller and airflow is weaker than before.

In addition to that a strict cleaning routine may make the use of an air purifier even more important. This is because of the cleaning solutions and chemicals that you are using may contain impurifications to begin with.

Do You Really Need an Air Purifier?

Millions of Americans think about purchasing an air purifier for their home or their business. For most people they just want to be able to breathe clean air.

Air purifiers capture harmful particles in the air by using collection grids or filters. These particles may even include dust particles and for any home that has a person suffering from allergies associated with dust, may very well find that an air purifier works to remove or completely eliminate your allergy symptoms.

Air purifiers can also help those with allergies that are related pets. You will find that multiple air purifiers not only trap pet hair, but they also trap the air particles created by pet droppings.

Air purifiers are also a good idea if you have young children at home. Children tend to be more susceptible to illness. With cleaner air, your child’s health may improve a lot

Air purifiers may also be ideal for those who are smokers. Even if you are not a smoker, there may be someone inside your home who is.They help a lot with reducing secondhand smoke. Secondhand smoke is bad for everyone, but it is especially bad for children. 

We have explained these in a lot more detail just below.

Air Quality for Kids in the Home

That becomes even more important if you have a new baby or kids in the home. Children do tend to be more susceptible to illness than healthy strong adults.

With cleaner air, your child’s health may improve a lot simply because they are breathing better quality air.

Many daycare centers use these to help reduce the spreading of common ailments like the cold and flu.

Asthma and Allergies in the Home

It is also an important consideration for anyone who suffers from asthma or this type of allergy. Air purifiers work to eliminate common dust particles, which is a common cause for allergies.

Homes with Pets

Others buy them because they have household pets. Pet hair and pet droppings can cause irritation when airborne and again provides a valid reason to purchase an air humidifier.

The family pet is a very big source of home pollution since pet dander contains allergens. . If they are allowed in a bedroom then we recommend that you run an air purifier constantly and wash your bedding daily if possible.

Any Home Where Smoke is Present

An air purifier will also be of great benefit to those who are smokers or if anyone inside your home is. If this is the case, you will want to seriously consider purchasing an air purifier. Most air purifiers, especially those designed specifically for smoking households, may help to reduce second hand smoke.

Here is an excellent video from the Consumer Report's team that challenge the thoughts about air purifiers in general.

So you can see from this that air purifiers help deal with smoke and dust, but do not listen to much of the other hype.

How Do Air Purifiers Work?

Air purifiers clean the air by removing harmful particles of dust from the air. They capture these in their collection grids or filters.

When purchasing one it is important to think about the initial cost, but I think it is even more important to think about the cost of replacing the filters. These humidifiers really only work and be effective if the filters are changed on a regular basis.

Some humidifiers use collection grids rather than filters. That means replacement of filters is not required, however the downside is, that these are usually more expensive to buy, so will cost you more upfront.

Types of Air Purifiers

You will not be surprised to know that there are lots of different types to pick from. These include:

  1. HEPA Filter Air Purifiers
  2. Charcoal Air Purifiers
  3. Air Ionizers
  4. Home ULPA Air Purifiers
  5. Single Room Humidifiers

Whole House Air Purifiers: Do They Exist?

Most department stores will only carry a limited selection of air purifiers. Theses smaller air purifiers are designed to purify the air in one and maybe up to two rooms.

That certainly gives out the impression, that this is the standard for what you can buy on the market. There are however larger options and these are referred to as whole house air purifiers.

The reason most retailers don't stock these is that they take up a lot of floor space. 

It is well known in the Retail industry, that all retailers try and place as many items inside their stores as they possibly can. Sometimes, larger items, especially items that may take up a large amount of space, are left out.

The reality is that these can be hard to find. It can also be hard to find someone who can offer really good advice on buying these. Some local home improvement stores may have these, so don't be afraid to shop around.

Technically, improving the air inside your home, especially the whole house, can be considered a home improvement project. That is why a large number of home improvement stores carry a selection of air purifiers, including those that are designed for the whole house.

Although whole house air purifiers are ideal, especially if you want to clean up the air inside your whole house, you will often find that they are more expensive, when compared to most traditional air purifiers. 

Air Purifier Buying Guide

An air purifier is simply an electric machine that is used to eliminate harmful particles or contaminants from the air. If used inside your home, air purifiers will help to make the air that you and your family breathes cleaner. That is their simple purpose.

If you have never bought one before then this buying guide should really help you out.

Despite the simple thing that these are designed to do, many buyers get it wrong because they primarily focus far too much on the price of the purifier.

Check Out What Is Available

Now we know that you will not want to pay more than you have to. We also know that you will likely want a purifier that looks the part. We would however highly recommend that you should take the time to understand the product you are interested in, then consider the price of the purifier, as a whole, and most importantly the overall performance quality.

We think the first step is to just familiarize yourself with all of your available options.

The best way is to visit a couple of your local retail stores. Have a look around but don't buy one. Use these visits to examine each product that they have available.

Read the information which can be found on the air purifier boxes. Make a brief note of sizes and prices of the products at the store. Take this information with you, either in a notebook or on your phone and then go back home.

Get on the internet and with the information you have you can not only familiarize yourself with the different air cleaning machines, but you can also read product reviews from customers who have bought and used the different models.

If you have the time read as many of these as you can as they will give you inside information on the operation and maintenance of multiple air purifiers. Although product reviews are nice, you are also advised to do your own research, as well as use your common sense. This is important, especially when determining the final cost of purchasing an air purifier.

Understanding Air Purifier Filters

Most air purifiers use filers to filter the air in your home. Some of these filters just need to be cleaned. However please be aware that some of them can not be cleaned and as such need to be replaced.

If you buy an air purifier then you should determine when that filter needs to be changed and exactly how much it will cost. This is extremely important, especially if you are shopping on a budget. The running costs for these can get high, and many people just stop buying the filters making their air purifier completely useless.

We would strongly recommend avoid buying an air purifier that regularly needs to have replacement filters. Many of these need the filters replaced every couple of months.

The reality is that the filters end up costing more than you originally paid for the air purifier.


We would recommend buying an air purifier,that uses HEPA filters. HEPA filters, can be expensive, but they are by far the best performing filters in terms of keeping the air in your home as clean as it can be.

The reason these are so effective is that these filters must meet specific regulations. These regulations, which are imposed by the Department of Energy, are the reason why air purifiers with HEPA filters are considered the most successful at eliminating unwanted or harmful air particles. 

Where Can You Buy Air Purifiers

Once you have completed your research and decided on which air purifier you are going to buy, then where can you get the best deal?

Air purifiers are sold all across the United States. Many Retail stores sell these including home improvement stores, home stores, and most traditional department stores.

Air purifiers can also be purchased online from a number of different retailers. For the largest selection of air purifiers, as well the ability to quickly compare prices, you may want to think about shopping online.

Honestly, where you shop doesn’t matter as much as which type of air purifier you are purchasing. If you are looking for an affordable, but well performing air purifier, you should be prepared to spend a little bit of time researching all of your available options.

While this research may seem time consuming, it will almost always be worth it in the long run.
