If you’re looking for the best cheap air purifier you can get, then this free guide was written specifically for you.
While many of the air purifiers you find on sale today range between $100-$300 dollars, we know that you don’t want to spend that much.
Instead, you want the best affordable air purifier you can get for the cheapest price possible. And, that’s exactly what we’re going to share with you in this post.
Below, you’ll find out what the best inexpensive air purifiers are between $30-$50, as well as how they differ from the more expensive options.
How an Inexpensive Air Purifier is Different from an Expensive One
When you’re looking for a cheap air purifier it’s important that you understand what it can and can’t do for you. This will help align your expectations with the device so that when you bring it home you’ll know what to expect.
The major differences between the cheapest, best affordable air purifier and an expensive one include:
- Maximum room size it can handle
- Filter type and efficiency
- Frequency of filter changes
Maximum Room Size it Can Handle
When shopping for an air purifier that fits your needs, you’ll find that the more money you spend, the bigger space the device can purify. When buying a low-cost air purifier, the first thing you give up is room size area coverage. This may or may not be a concern to you, but it’s important to keep in mind.
The best cheap air purifiers we recommend below can purify a room between 80-200 square feet (sq. ft.). If you are just looking for a unit that can cleanse the air for a bedroom, a small living room or office space, this is all you’ll need.
There’s no point in you spending extra money on an expensive air purifier that can purify a room up to 500 sq. ft. when you don’t even need it. Expensive air purifiers are mostly geared toward purifying very large rooms or an entire level of a house. (See our best home air purifier guide for those options.)
Filter Type and Efficiency
The second thing that differentiates the best inexpensive air purifier from an expensive unit is the type of filter it uses and the efficiency. This feature is really only a major concern for people that suffer from severe allergies or asthma. Others who don’t have these problems and just want cleaner air around them will do fine getting a cheaper, affordable air purifier that doesn’t use the top-of-the-line filtering technology.
With most low-cost air purifiers you’ll find that they use a HEPA-grade or HEPA-type filter, not a True HEPA filter. What this means is that they can only remove harmful toxins from the air that are as small as 2-5 microns in size (such as pollen).
A True HEPA filter can trap particles as small as 0.3 microns in size (such as dust mites, pet dander and bacteria). While a True HEPA filter is the most expensive type of device to get, if you don’t suffer from major allergies or asthma issues, a HEPA-grade or HEPA-type filter will most likely be fine.
Note: Our #1 recommendation below actually includes a True HEPA filter, ensuring the highest level of air quality control.
Frequency of Filter Changes
The last thing that makes low-cost air purifiers different from expensive devices is the frequency of filter changes. In general, high-cost units usually have a larger filter that can trap more toxins and particles than a cheaper air purifier. Most affordable air purifiers are smaller devices with smaller filters. This can require more frequent filter changes. Keep this in mind when purchasing a low-cost unit.
Note: Our #3 recommendation below actually has a permanent filter that can be vacuumed clean. Eliminating any cost for a filter replacement.
Best Cheap Air Purifier Recommendations
#1 Best Affordable Air Purifier
Hands down, this is the best affordable air purifier you can get.
Unlike any other device in this price range, this unit is actually equipped with a True HEPA filter, removing 99.97% of airborne contaminants 0.3 microns in size. This is the main reason for why it made as our best cheap air purifier.
What we like most about this product is that it includes a 3-in-1 filter that requires just one replacement. This makes filter replacement easy to do and affordable.
The included carbon filter removes odors and the PCO filter and UV-light work together to capture and dissolve bacteria and mold spores. This added feature helps you stay healthier since these harmful contaminants are removed from the air.
What’s even better is that this small device is powerful enough to purify a space up to 200 sq. ft. At this price point, you won’t find any other air purifier that’s this powerful.
#2 Best Inexpensive Air Purifier
While this device only uses a HEPA-type filter, it still made in onto our list for several reasons.
For starters, it requires only one filter to change, which is a big convenience, and very affordable.
Second, it includes an ionizer that delivers extra cleaning power against airborne bacteria and viruses. This feature emits ions into the air that latch onto harmful particles and pulls them out of the air.
Third, it gives you the option between 3 fan speeds, allowing you to control the efficiency of the product at the touch of a button.
Finally, it can sit on its side or upright, allowing it to fit in the tightest of spaces. You can place it on a desk, under a table or in the corner of a room
The only drawback to this product is that it can only purify a space up to 80 sq. ft., which is only ideal for small rooms and offices.
#3 Best Low Cost Air Purifier
Our final recommendation for an affordable air purifier is the Honeywell HHT-011.
This product made it onto this list for two reasons:
1) it doesn’t require any costly filter changes
2) its received over 2,000 positive reviews on Amazon
What we like most about this device is that it uses a permanent HEPA-type filter, which saves you costly filter replacements. Als,o you need to do is vacuum it to keep it clean and free from dust and other allergens.
It also includes an optional ionizer for extra cleaning power against airborne bacteria and viruses. Similar to our #2 recommendation it zaps harmful particles that make you sick.
The pre-filter, which traps the largest particles, is washable and reusable – another cost saver.
Another nice feature is that it includes an optional nightlight, which is great for a bedroom setting.
Similar to our #2 recommendation, this air purifier can only purify a space up to 85 sq. ft. which means it’s only good for small spaces.
