14 Things To Look For In A Cheap Air Purifier

Many people think that air purifiers are only for those who suffer from allergies or asthma. Even though air purifiers can be a good idea for those people, they can also help everyone else by making the air in their homes cleaner and healthier to breathe.

The best air purifiers should be able to remove more than 99% of airborne particles. Look for the term “true HEPA” in the description, which means that the filter is certified to meet rigorous standards.

If you want to buy an air purifier but don’t want to pay a lot of money, here are 14 things to look for in a cheap air purifier.

1. CADR Rating

Clean Air Delivery Rate (CADR) is a rating system created by the Association of Home Appliance Manufacturers (AHAM). It is used to help consumers make better-informed decisions about what type of air cleaning equipment they need.

There are three different CADR ratings; one each for tobacco smoke, pollen, and dust. Each rating should be at least two/thirds as large as the room’s square footage.

2. Does it have a HEPA filter?

HEPA filters are probably the most efficient at removing particles from the air. The best HEPA filters can capture up to 99.8% of particles as small as 0.3 microns. However, you need to know that not all HEPA filters are created equal! Some cheaper ones might not be able to trap those smaller particles that are floating around in the room.

If you want something that will effectively remove PM2.5 and smaller particles from your house, make sure you get a true HEPA filter.

3. Does it have a carbon filter?

Carbon filters are commonly used to remove odors and gases from the air. This is especially useful if you live close to a factory or dumpsite that emits unpleasant smells into your room.

However, not all carbon filters are made equal either! There are different types of carbon filters such as activated carbon and granular activated carbon (GAC). Activated carbon is what’s used in smoke detectors and air fresheners for its ability to absorb smells and chemicals like formaldehyde, hydrogen sulfide, benzene, etc.

It’s often included in conjunction with a HEPA filter as a pre-filter stage or as part of the HEPA filter itself. Most carbon filters are only effective against odors and chemicals, so they won’t help with pollen or smoke unless used in conjunction with a true HEPA filter.

4. Does It Really Filter Air?

The biggest mistake people make is choosing an air purifier that looks good and is priced well but doesn’t do its job. A poor-quality air filter won’t clean the air as much as you need it to, leaving you with contaminated air instead of clean, pure oxygen.

The best way to ensure that your new air purifier will actually filter air is to go with a trusted brand known for its quality products. Companies like Honeywell, GermGuardian, and Whirlpool have been around for years and have built up their reputations by manufacturing high-quality home appliances that do what they say they’re supposed to do.

5. Does It Work Well In Allergies?

Allergies are one of the most common reasons people purchase an air purifier in the first place, so if you’re shopping for a budget purifier, it’s important to make sure it will work well for this problem. After all, what good is a cheap air purifier that doesn’t do its job?

Most air purifiers will claim to be effective against allergies, but some models go above and beyond the others. The best air purifiers for allergies will have a HEPA filter that can remove 99.97% of particles 0.3 microns or smaller from the air (which includes many allergens) and uses at least 4 stages of filtration to trap these particles in different ways.

These filters should also be able to remove pollution and gases, which are also common triggers for allergy sufferers.

6. How Much Space Will It Cover?

You need an air purifier that is able to clean up the amount of space you have available. The last thing you want is to purchase a small unit only to find out it doesn’t work in large rooms.

You might be able to find a cheap air purifier that can cover 1,000 square feet or more, but it’ll be a lot bigger and bulkier than one that only covers 200 square feet. That’s why the first thing you need to do is determine how much space you want to clean.

This might seem obvious, but many people don’t realize they’re looking in the wrong section of the store. Or they buy something that’s too powerful for their needs and wind up paying more than they would have if they’d just gotten the right model. So… measure the room you want to purify and then look at models that are rated for that much space.

7. Is It Energy-Efficient?

Check whether or not the unit has energy star certification before you buy it because energy-efficient units have lower electricity costs and less carbon dioxide emissions over their lifetime than standard models do.

If you want to save money on your electricity bill and if you want to help the environment, you should choose an energy-efficient unit to use in your home or office.

8. Does It Have A Powerful Fan?

You already know that an air purifier needs to have a fan to circulate the air through the machine. But did you know that some fans are more powerful than others?

The most powerful fans can move 3,000 cubic feet of air per minute (CFM). This is an industry standard that all manufacturers adhere to. If a manufacturer claims that their fan can move more than 3,000 CFM, then they’re lying.

9. Is It Easy to Clean?

You’ll need to clean your filter regularly if it’s going to stay effective — on average once every two months. Make sure you choose a unit that’s easy to take apart and reassemble after cleaning so you don’t damage any of its components when cleaning it out.

10. Is It Quiet?

The noise level is important, especially if you plan on placing the unit in your bedroom or living area. Noise levels are measured in A-weighted decibels at high speed (dBA). Most units run between 40 and 60 decibels, which is about as loud as a normal conversation. If you’re concerned about noise, look for a unit with a lower dBA rating or multiple fan speeds that allow you to adjust the power and volume of the unit.

11. How Often Will You Need To Replace The Filters?

Some filters can last for years without needing replacement, but others need frequent attention to function properly. Check how often you’ll need to replace each filter before buying an air purifier so you know how much it will cost in the long run.

12. Do You Need Wi-Fi Connectivity?

Some models allow you to control them via smartphone apps or through smart home services like Amazon Alexa or Google Home. While this may be convenient, it’s not always necessary. If you aren’t interested in controlling your device with an app or voice assistant, there are plenty of non-connected options that can do the job just as well at a lower cost.

13. Is It Portable?

If you want an air purifier that can move from room to room easily, look for one that is light and has a carrying handle. A unit’s portability should also be considered if you plan on taking it

14. Does It Have A Night Mode?

If you plan on running your air purifier while you sleep, look for a model with a night mode to keep it quiet while it operates. Some models even have LED lights that turn off during this mode so they don’t disturb you. If your device doesn’t have this feature, make sure the light is dim if it’s on all the time.

Let’s look at some excellent cheap air purifiers that will do the job…

In summary, there is not much separating the smoke air purifiers on this list as they are all very good. In fact, the units listed towards the bottom are actually much higher sellers and the clear crowd favorites based on the volume of sales.

That being said, I do lean towards the KOIOS Air Purifier as the best air purifier for under $50.

The comments left by the consumers just appealed to me slightly more than the others and so it is my number 1 choice. However, I can’t see you going wrong with any of the above machines.
