Good air quality starts with clean air, so if you’re wondering “how many air purifiers do I need?” then we’ll answer that question. This guide will help you figure out your ideal air purifier setup at home (or in the office, hospital clinic, or wherever you are).
Different rooms need different setups depending on their means of ventilation, room size, ceiling height, number of items in the room, people who stay there, and the air pollution levels outside. We care about your indoor air quality and that’s why we want you to choose the right number of air purifiers for your needs.
When you don’t put enough air purifiers for a large room (or a highly-polluted room), you not only waste energy (and bucks) but also time, since air purifiers that aren’t rated for such rooms will take many hours to work.
Where should air purifiers be placed?
To get the most out of your air purifier, here are the best spots to place them:
- Top areas. Make sure you place your air purifier in high places with enough clearance to avoid its power being blocked by objects. A good rule of thumb is at least 5 feet off the ground.
- Near the source of pollution. If you notice areas where funky smells or dust often settle, that’s a good spot for an air purifier.
- Keep them away from appliances. Since most air purifiers have a remote control, some appliances can interfere with the settings of the unit.
- On the wall. If your air purifier is mountable on walls, you can install them that way, especially in kitchens. They not only save space but also clean your area more efficiently.
- Away from moisture sources. If you’re running a humidifier, keep the air purifier away because it can absorb the moisture and ruin the filter. The same is true with other sources of humidity, such as bathrooms or near windows if the season is cold.
Do I really need an air purifier?
Yes, you do! Air purifiers are beneficial for you and your family (and guests) because they are capable of lessening the pollution from the air you breathe.
With that said, Amazon is a great place to start because they have many available air purifiers for various home or office setups. So if you’re asking “what air purifier should I buy?”, here are some suggestions we’d like to share with you:
For Kitchens: Winix 5500-2 Air Purifier
With a rating of up to 360 square feet, this one boasts a Washable AOC Carbon Filter, which makes it ideal for kitchen smells, pet odor, and the like. It also doesn’t use ozone thanks to the PlasmaWave technology on removing VOCs and other funky odors. Like most air purifiers today, it has a true HEPA filter and smart sensors that adjust the fan speed as needed.
There is even a sleep mode to avoid disturbance at night, in which the display buttons are dimmed to make sure you won’t be affected by light distraction. You can easily change the settings using the included remote control.
For Bedrooms: RENPHO Air Purifier for Allergies and Pets
If you want a bedroom air purifier that’s easy on space, this is a unit for you. It is applicable for spaces around 240 square feet and is only at 26 dB on its noise level so it won’t disturb sleeping babies at night. It has a 4-stage filtration system, which includes H13 true HEPA, antibacterial, activated carbon, net filter, and pre-filter.
With 3 fan speeds to choose from, it also has a night light for the little kids. The air purifier can be set for 2, 4, or 8 hours on its timer to avoid consuming too much electricity. What we like is that the night light is colorful and is not too bright for a distraction. As it is meant for babies and kids, it is free from ozone and UV-C so it is also eco-friendly.
For Living Rooms: Germ Guardian AC4300BPTCA Air Purifier
To serve guests with clean and healthy air, this air purifier sports an electrostatic HEPA media air filter, which captures up to 99.97% of pollutants. It has a total of 3 fan speeds and it has a UV-C light for disinfecting the air (can be turned off when not needed). There is even an ultra-quiet sleep mode if you want to relax or place it in the bedroom.
This unit is applicable for spaces up to 153 square feet. The programmable timer allows you to “set it and forget it” while the odor-reducing activated charcoal filter will help to reduce funky odors around the room. It even has a filter change indicator so you will know when it’s time to replace the HEPA filter (to avoid spewing back dirt and debris into the air).
For Large Rooms: Alen BreatheSmart FLEX Air Purifier
For spaces up to 700 square feet, this one has a true HEPA filter (H13 medical-grade) so it is ideal for homes with people who have allergies and asthma. With 4 fan speeds, it is CARB-compliant and Energy Star certified. It even has different filter options (pure, fresh, and smoke) depending on your needs.
You have various panel colors to choose from to match your interior design. Consuming only 36 watts, its maximum noise levels are only 55 dB so it’s not too loud.

If you don’t know what size of air purifier you need, whether it’s for a small room or an air purifier for a large space, here’s a table that will help you decide:
| Air purifier rated size | Applicable rooms |
