From the name you easily get what is the exact job of an air purifier, it filters the dust particles, pet dander and unpleasant odor. Talking about price, around $50 sounds very much cheap price for air purifier. Even some brands undermine the quality of filtering and building material to keep the price at around $50.

Here we have come up with the best air purifiers under $50 for those who want the price in affordable range and don’t want to be deceived by the inferior types of air purifiers.

Why do you think you should read this content? Because the comparison chart and the details of the air purifiers will provide a good idea about which air purifier will be best for you. To buy the best affordable air purifier, you must sacrifice a couple of features. So read through the content and which features are for you and which are not.

How Do We Measure?

It’s an easy task to make a list of the best air purifiers under $50 if we don’t take quality over quantity.There are many air purifiers under $50 hence it is tough to make the list of top 10. Because we don’t prioritize any fancy features but the basic features with excellent performance. That’s why here you’ll get the ideas about which features we have focused on and which are not important to us.

Filtration Method

Filtration method is our first thing to look at. The main purpose for having an air purifier lies in this feature.

  • HEPA Filter: High-Efficiency Particulate Air (HEPA) is a filtration system that tarps tiny and fine particles like dust particles, dander and the particles we can’t see in naked eyes etc. specialists of air purifiers recommend True HEPA filter because it works like a shield against the particles of minimum 2 microns.  Here we have tried to find out an H13 or H14 the maximum tier of HEPA filter. But it doesn’t matter if we got the latest HEPA or not. All HEPA filters provide 99% efficiency.
  • Carbon Filter: Our first target is to manage a HEPA filtration system. Now if we get an additional filtration system like a carbon filter, nothing will be better than this. Carbon Filter revokes smoke and unpleasant odor. It is as well important as HEPA filter because harmful smoke causes asthma and allergies. It’s tough to get both HEPA and carbon filter hence we have found several.

Room Coverage

Another important and must require measurement. best air purifiers under $50 have room decent room coverage. But still, we eliminated the air purifiers which have HEPA and Carbon filter but don’t a decent room coverage. We will see CADR (Clean Air Delivery Rate) value on every air purifier, don’t get confused and think of this value as a room coverage.

Ozone Less

Most air purifiers produce ozone and it is quite harmful to our health. It doesn’t sound any good to replace slightly polluted air with ozone. That’s why we tried to find out the 100% ozone less air purifier and put them on our list.

How Often Filters Need to Replaced

No matter what filtration system you have, replacing the filtration system is a must after a certain period. If the air purifier $50 needs a replacement filter frequently, it sounds no more convenient. So, filter replacement routine, replacement method, and cost, etc. are the influential measurements.

Things to Consider when Buying the Best Cheap Air Purifiers Under $50

It is not about just cleaning the air which you have no idea about. Putting the right purifier for the right room will obviously clean the air beside it will keep your mind fresh and can bring happiness. We have already discussed the points which are crucial to us before making the list. Now it’s your time to focus on the things you should always keep before purchasing under $50 air purifier.

Building Quality and Magnitude

Definitely, best air purifier under $100 will be a budget purifier. And here we are discussing under $50. So, don’t expect all the good qualities in this kind of budget range. Most of the air purifier around $50 has built with hard grade plastic. So plastic sounds tolerable for budget air purifier. But ensure they are not built with low-grade plastic.

Size matters most in this case. It is as simple as doing a summation of 1+1. The smaller the magnitude will be, the small room it will cover.

Room size

We have already brought the discussion about room size. It means how much space the under $50 air purifier going to cover. Our suggestion is to be exquisite in this case. Before selecting the right air purifier, just make sure the measurement of the rooms where you have the possibilities to keep the purifier.  Here we got a right-hand rule for you guys.

  • Measure the room size in sq. foot
  • Now pick the air purifier unit which has the ability to cover that space with a minimum of 2 air changes per hour.

Also, there is a measurement criteria for an air purifier which we use for finding the ability if air purifier. CADR (Clean Air Delivery Rate). You will get the value on the box. But we have doubt if CADR value is telling us the perfect value for the cheap air purifies. Most of the case, this value is just a number for under $50 air purifiers.

Filtration System, Lifespan and Cost of Filter Replacement

Look for the 3 stages air purification system. Pre-cleaning, True HEPA and Activated Carbon. Pre- cleaner eliminates the large particles like our hair and when air passes through this layer, only 3 microns of airborne particles still there into the air. True HEPA can filtrate pollutants as tiny as 0.3 microns. It is the main part where the best air filtration organizes. Finally Activated Carbon Filter is for only eliminating smoke, the smell of chemicals and other unpleasant odors. Additionally, inclusion of an Ionizer will ensure the best possible smell removing operation.

The small the filtration system will be, the less it will anticipate. Most of the case, 4-6 months is a negotiable range for a cheap under $50 air purifier. But filter can last less than that, it depends on how bad your air quality is and how much time you run the unit.

Filter replacement is a must for all sorts of filtration. It depends on the model of True HEPA filtration system and the range of time you need to replace the filters. The quickly your filter’s lifespan will send, the much replacement cost you have to carry.

Noise Level

Noise level should be around 50dB at high-speed operation. And for sleep mood, don’t get an air purifier which has a noise level of around 35dB. Less than 25dB should be the choice for sleep mood and you will get this kind of silent air purifier in this price range easily. So no worries.

Certification

Certification is not only for air purifiers but before buying you should find they the product is certified by any renowned certification method. If your air purifier meets the strict safety measurements of CARB and ETL, then you have nothing left to think about its actual safety for human health.

Cheap small filters need to be replaced frequently.Larger filters need to be replaced once a year.

Do You think Your Air Purifier is Under-Performing?

Obviously, under $50 air purifiers have some limitations. And if you push further on those limitations, the performance will be hampered.

  • For example, simply you can’t desire your Holmes Desktop to perform in 300 sq. ft. room where the suitable performer is Levoit lv-h126 air purifier.
  • Don’t run the air purifier while windows are open. It affects performance.
  • Maybe you are not cleaning the filter regularly. Don’t blend up the two things, cleaning the filter and replacing the filter. Replacements need once or twice in a year but cleaning needs to be done frequently.
  • It won’t work if you keep running the medium fan speed or sleep mode on a heavily contaminated room like the kitchen.

FAQs

How often should you keep air purifier on?

12 hours a day is the perfect choice to run your air purifiers. Sometimes the hum noise makes your head sore if your rum the purifier at night. But the simple thing is, the more you will run the more you will get clean air and the more you have to spend money on replacing the filters.

Are air purifiers really worth it?

It’s a burning question and people are still flummoxed about the performance of the air purifiers. The certification of EPA and ETL indicate the real work. And if you go through the customer’s review, you will see most of them are talking about the decreasing rate of probability of becoming sick.

What air purifiers do doctors recommend?

Often doctors prescribed air purifiers, they tell to use an air purifier. Specifically, for asthma and allergies, they recommend HEPA filter. 

Final Thoughts

It’s a true fact, affordable, cheap, budget and under $50 air purifiers have lacked some features. Even though they cover most of the features, those features are not at the highest point of rank like expensive air purifiers. To obtain the best air purifiers under $50 in 2021, the top notches are quality, performance, room coverage and filter’s life span. These things can only help you to get the best output.
