There are plenty of reasons to get an air purifier.

Even if you’re free of the pollutants, there are plenty of toxins to worry about. In fact, according to the EPA, some air pollutants can be up to five times worse indoors compared to outside!

Luckily, it’s hard to go wrong here. Though there are a lot of little tips and tricks to get the most out of an air purifier, which I’ve combined in this quick guide.

Ready to get the most out of your air? Then let’s get started.

Fourteen Ways to Get the Most out of Your Air Purifier!

Air purifiers are deceptively simple. You just set them up, turn them on, and they go to work… right?

Well, that’s not the whole story.

While that certainly will get your air purifier doing something, how well it cleans the air is based on how you treat it. Poor use of an air purifier will lower its efficiency by up to half! Don’t worry, though. By carefully following these tips, you could improve efficiency by up to 20%!

1. Close those windows

Much like running an air conditioner, you don’t want to pay to treat air that’s just going to leave your house anyway. However, if you really need those windows open, the air purifier can still get a surprising amount done!

2. Target problem spots

Run your air purifier in the areas that have what you want to combat. If you’re getting wildfire smoke, put it by the windows. If a room has a particular mold or odor problem, get the purifier in there. If your mother-in-law likes to smoke in her bedroom, give her a purifier to herself.

3. Don’t exceed its limits

An air purifier is only rated for a certain area. If you have a six hundred square foot great room, and your air purifier can only handle two hundred square feet, you won’t see much of an impact.

4. Check the filter

Most devices that circulate air other than fans have a filter, and your air purifier is likely no exception. When this filter fills up, it can become difficult for the device to cycle air through. Follow your manual’s instructions on how to clean or replace the filter.

5. Don’t be afraid to switch it up

Many air purifiers are relatively lightweight. This mobility is a great advantage You can clear out your room for a pollutant-free night’s sleep, and then still purify the living room before company arrives. By giving your purifier access to more areas, it can treat more air, increasing its efficacy.

6. Give it some breathing room

An air purifier can only clean the air that reaches it. If you block some of it with furniture, laundry baskets, or a coatrack, you’ll decrease its efficiency. Try to leave it with at least a few inches of clearance all around.

7. Give it some breathing room

No, you didn’t misread that. This tip is so important, we’ve listed it twice. Remember that airflow is vertical as well as horizontal. Putting your air purifier under a table will severely limit its efficiency, even if it has a lot of room all around it.

8. Intake out

Make sure that your air purifiers intake vents are always the clearest of obstruction. If you have it near a wall, that means facing these vents into the room. This allows it to most easily take in air to clean.

9. Avoid those corners

Furniture and belongings aren’t the only threat to that necessary airflow. Putting an air purifier in a corner blocks incoming air from half of the possible directions. If you end up having to put your purifier near a wall, try to put it in the middle of it instead of the corner. Thankfully, there’s a good workaround:

10. Lift it up

With their generally portable size, air purifiers can fit on many tables, and even some more generous and stable stools. Not only can this help keep it from the clutter underfoot, but the airflow a few feet off the ground is more active, improving function further.

11. Go where the action is

The air in your home is constantly moving. This is most pronounced in doorways and by windows, but even in the center of a still room, there’s a slow circulation. By placing your air purifier where air moves more, it has access to more air to clean.

12. Get off that wavelength

It might not be as intuitive as some of the other tips, but some of your other appliances can interfere with your air purifier. Televisions, microwaves, and even speakers can give off electromagnetic waves that hinder the purifier’s function—and the purifier can interfere with them as well! Try to give it some distance.

13. Go set a watchman

The air purifier can also work as a sort of doorman, letting good air in and keeping the bad stuff out. If you want to keep a room free of the pollutants in the rest of the house, set up the purifier near the doorway. This is great for baby rooms or to keep pet hair or cigarette smoke out of rooms where you don’t want it.

14. Water stays wet

This one might throw a wrench in the works. The two rooms in the house that get the most humid are the bathroom and the kitchen (boiling water throws off a lot of steam). These also tend to be smellier and more mold-prone areas. However, the heavy, wet air won’t be dried out by the air purifier. For that, you’ll have to look into a dehumidifier.

Other Tips: Which Room and Where?

While the air purifier pros move their units wherever they need them whenever they need them, it’s good to know what impact to expect. In addition, it’s nice to know how to get the most out of the purifier regardless of what room it’s in.

Here’s a room-by-room guide to your air purifier’s continued success.

The Bedroom

An ever-popular choice, the bedroom certainly seems like an ideal place for an air purifier. After all, we spend roughly a third of our day in that room. If we get benefits from purified air anywhere, it’s going to be here. Besides, most of us would try anything to improve our sleep.

The difficulty with putting an air purifier in the bedroom is the airflow itself. Depending on season, humidity, and personal preference, being battered by air, however clean, can hurt sleep and cause headaches and sinus problems in the sensitive.

The solution to this is simple. Treat yourself as well as the air purifier and give yourself some space!

Set up the air purifier at least six feet from your head (the foot of the bed is a great place for this). Not only does this protect you from more dramatic air speeds, but it can keep the noise level down to a calming white noise level rather than a dull roar in your ear.

Don’t worry! As long as the air purifier is rated for your room size, you’ll still be getting that refreshing, purified air.

The Baby’s Room

A lot of parents worry about…well, everything. Introducing a new appliance into your precious child’s life can provoke a lot of anxiety. Can an air purifier somehow endanger a baby?

The answer to that is a gratifying one: no! Or, at least no more than any other electrical appliance (cords and outlets will never be danger-free). The purified air is even more beneficial to a baby than to an adult, as their tiny lungs are far more sensitive to pollutants and toxins than ours.

The only points of caution are to keep tiny fingers away from the appliance and plug, and to make sure that the sound isn’t disturbing your baby’s sleep or muffling the baby monitor.

The Kitchen

You might be thinking that the kitchen is a no-go for the air purifier. After all, didn’t you just read that the appliance can’t do anything about humidity? And that’s true, but is your kitchen always filled with heavy, wet air?

When the relative humidity is below 50%, an air purifier can do wonders in a kitchen! Not only can it clear away the smells of whatever you cooked or whatever burned in the oven, but if you put it near your trash can, it can prevent that awful realization that something’s beginning to rot three days before garbage day.

Just make sure your air purifier has a carbon filter so it can really tackle the smells!

The Living Room

The advantages of setting your air purifier up in the living room are plain. Outside of the bedroom, this is often the place family members (and guests!) spend the most time. There’s no special rules or tips for this room—put the appliance wherever it gets good airflow but stays out of the way.

The Bathroom

Much like the kitchen, the bathroom can be a terrible place for an air purifier. Not only do hot showers send out a lot of steam, but the bathroom is often as small as a closet. However, the very moisture that the appliance won’t do anything about actually means the bathroom can be the ideal place to use the air purifier.

Mold loves nothing more than damp environments, and most of us have dealt with some in one bathroom or another. An air purifier in the bathroom won’t reverse a mold problem, but it can filter out the microscopic spores in the air, stopping mold from ever getting started.

The downside, of course, is that you might have to move your purifier back and forth all day. But if you can prevent mold, that might be a worthy price to pay!

The Entryway

Putting your air purifier at the main door to your home has some big advantages. Not only does the area get increased air flow with both the foot traffic and the doorways, but this is also where a lot of outside pollution can enter the home. Your air purifier can do a lot of good here.

The only thing to worry about here is the area afforded to the purifier. Many entryways are small, tight spaces and that means the air purifier will either be in the way or in a corner. If you have a table here, it might be the perfect space to set up your appliance.


An air purifier is a welcome addition to any home. It’s hard to use one really badly, but there are a whole lot of ways to make it work better for you. Use the tips that work for your situation, don’t sweat it if you have to break a rule or two, and relax! Now you can breathe easy!
