Air Purifiers Buying Guide

It’s important to keep ourselves and our families healthy, no matter what the circumstances are.

However, with Coronavirus it’s vital to be even more vigilant with the measures we take to keep our homes clean. Keeping the air clean can help to reduce or even eliminate the virus, and that has no price.

With that being said, now that you’ve had the chance to read about the 5 best home purifiers, have you decided which model is the right one for your home? If you’re still unsure there’s no need to worry.

We know it can be hard to choose just one when there are so many great ones to choose from. That’s why we’ve taken it upon ourselves to write up the user-friendly buying guide below.

This guide will take you through each step to ensure that by the time you’re finished reading, there will be no doubt which is the purifier for you!


What is the best air purifier size for you and your home? It can be difficult to determine, as many people have the idea that they’re a kind of one-size-fits-all machine. However, that couldn’t be further from the truth.

An easy way to figure this out is by simply taking a look at the square footage rating of the model you have your eye on. Then, compare it to the size of the room you’re planning on placing it in.

You need the purifier to be either equal or greater than the room size, otherwise it’s honestly just going to be a waste of cash.

Placement Considerations

The truth is, you’re probably not going to get the most out of your air purifier if you just plop it wherever you feel like. Placement of the device is going to play a huge role in its effectiveness.

Sure, it may suit the square footage of your room, but if you’re putting it in an incorrect place it’s not going to work as well as it was made to.

For air purifiers which use a HEPA and/or Carbon filter, they’re going to rely heavily on the fan to pull in dirty air and push the clean air back out to be circulated.

If you place the model under a desk, behind a sofa, against a wall, or just generally somewhere where this airflow is being blocked, performance will be hindered notably.

The ideal placement for these are 2-3 feet away from any wall or piece of large furniture.

Models which use ionic filtration do not use a fan, though emit ions in a complete circle which means that you should place it in the center of a room to avoid blocking it at all.


As most of these models we’ve covered are designed to be used in a single room, there are probably going to be times where you need to move it to clean the air in another area of the house.

Air purifiers vary widely in weight, though what makes them easier to move are carrying handles and/or caster wheels.

The carrying handle means you don’t have to deal with awkward carrying and the casters let you roll heavier machines with ease.

Maintenance Costs

While most of us obviously take a look at the price tag on an air purifier, some of us overlook maintenance costs. Air purifiers, as one can imagine, operate best when they’re correctly maintained.

Make sure you know what that consists of for your purifier and how much that’s going to cost you.

Those that use HEPA or carbon filters are going to demand regular filter replacements, as they trap particles and will eventually get too clogged to work well.

The filter life, then, will depend on the air quality in the room it’s placed in. Realistically speaking, they’ll last anywhere from a few months to a year, and filters typically cost around $15 to $50.

Noise Level

Air purifiers which use a HEPA or carbon filter always need to use a fan to draw the air in and push the clean air out to catch the unwanted particles.

Fans obviously create noise, but the slower the fan is moving, the lower that noise is and vice-versa.

If you’ll be using your fan in an area where you need to hear others or concentrate, then you’ll need to pay special attention to this. If it’s too small for the room, then it’s going to run at higher speeds than it should to try and compensate.

Energy Consumption

Just like any other home appliance, air purifiers need electricity to run. As they’re running continuously, you must look at how much energy it needs to run.

Most will use anywhere from 5 to 200 watts of power, though if you want to make it easy on yourself and the environment, just opt for a model that’s Energy Star-rated, which will make sure it uses the lowest amount of energy possible, also making it more affordable for you to use.


Before you make your final decision, we greatly recommend you look at the manufacturer’s warranty to help steer clear of any future issues you may have with it.

Make sure you know what exactly is covered and for how long. These are all investments, so you don’t want to have to keep replacing them over and over.

While it’s not a rule, it seems that the more expensive the model is, the longer the warranty is that comes with it.

This can overall end up saving you some money, as you won’t have to shell out the money for a replacement if it starts giving you issues and it’s not covered.


The following features may not be something that will overall convince you to purchase or not purchase a particular model but can definitely influence your final decision and make your user experience more pleasant. They may be more expensive most times, but it’s more than worth it!


These filters catch the biggest particles, like hair and dirt. They help to lengthen the lifespan of other internal filters, and are usually washable/reusable for the entire length of time you have it.

Digital Controls

These are often more natural and convenient to use, as most of us already feel it’s more natural to use digital interfaces. Not only that, but when you compare them to a rotary dial or push buttons, they’re quicker, more intuitive, and more precise!

Adjustable Fan Speeds

As you can see from the products above, you’ll get anywhere from 2 to 5 fan speed settings, ranging from Low to High fan speeds. There are even select products with Turbo Speed modes which work to quickly clean up the air as you wish.

Filter Replacement Indicators

These are always nice to have, and are a light/lights that let you know when you need to replace the filters after they’ve become too dirty to work effectively.


The timer automatically turns off the machine after a specific time interval of your choosing. Usually it’s every 2, 4, or 8 hours. This feature helps to save energy and keep it going the entire time you’re out of the house.


These not only look cool at night, but helps you to easily spot the air purifier in a dark room.

FAQs – Air Purifer Questions

Q: Can’t I just use energy-efficient windows and doors to keep out viruses?

A: While these can definitely help in many ways as far as keeping pollutants out, they can also trap in the stuff we don’t want! This has been proven by the Environmental Protection Agency, which states that indoor areas have around a 2-5x higher concentration of certain harmful pollutants than outside.

Now remember that most Americans spend around 90% of their lives inside, and you can see why they’re so important!

Q: What do air purifiers really help with?

A: They’re great at filtering out dust, smoke, and pollen from the air with HEPA filters. However, there are many (like those on our guide) which can even reduce bacteria and viruses that can potentially make us ill.

Q: Are activated carbon filters better?

A: They’re not necessarily “better”, though there are some great benefits to them! They are excellent at catching odor-causing molecules from the air and can even get rid of some gases. However, they won’t do much against formaldehyde, ammonia or nitrogen oxide.

Q: What are ACH and CADR ratings?

A: You may have seen that certain models on our guide have these ratings. ACH is often overlooked by consumers and stands for “Air Changes Per Hour”.

It’s one of the biggest factors in how efficient a purifier is, telling you how often the model can exchange the air in a room with clean, fresh air, per hour.

For example, a 4x rating means it can take the “dirty” air in a room and exchange it with clean air 4 times in an hour.

CADR stands for “Clean Air Delivery Rate” and can help let you know how well it can clean the air in a certain size of room.

Many manufacturers make claims that aren’t backed up, so those with CADR ratings are good to have as they’ll give you a real assessment of how large of a room a certain model can handle.


Now that you’ve had the opportunity to read about just about anything you could ever want to know about the best 5 air purifying machines for Coronavirus, which one will you be using in your home?

If you still haven’t decided, you can rest easy knowing that no matter which one you select, you’ll be getting one of the top models on the market today.

However, what’s most important is that you select the one that works best for your needs, environment, and room size. We hope that our guide has helped you to do just that. Thanks for tuning in and we’ll see you again soon!

Using HSA/FSA funds to purchase on Amazon can be a great way to reduce taxes and reduce overall healthcare costs for items not covered under medical insurance. Users of such medical savings plans are issued a debit card by their provider, which can be added to their payment methods in their Amazon account.

Whether items sold on Amazon are deemed as eligible for HSA/FSA plans remains the responsibility of the buyer and their particular health plan provider. It’s ultimately up to the IRS and participating health plan providers to deem which medical and health products are considered eligible for the payment plans.
