Expert’s opinion

If you only want a basic air purifier then Hamilton Beach TrueAir Air Purifier is unconditionally perfect. A permanent HEPA grade filter makes it unique. But you should keep an eye on the filter because there is no replacement indicator. It also not recommended for the extra sensitive patient.

Expert’s opinion

Very good for basic needs. Lightweight and compact size increase the portability. But for the moderately sensitive body, try to keep it in a safe zone and don’t shake it hard. Another concern is the nightlight. Although the light is cool and fine it can’t be turned off when the purifier is running. I suggest, if you feel disgusted just remove it out of the machine (you can learn it from YouTube)

Holmes air purifier HAP242

If you search a super economical, compact, handy ionizer air purifier then Holmes air purifier HAP242 is the best option for you. Its dual position and three-speed settings made it more efficient.

What users say?

Paul, a user said that this product is quite good for him. He can’t explain how good its performance compared with another desktop air purifier. Although its low and medium speed is quiet high speed is slightly loud. So he does a hack, only run it high speed when he is out of the home.

Expert’s Opinion

Very good option as a compact design ionizer and light desktop air purifier. Also, very affordable and fits for all financial status. Although Ionizer light increases its efficiency, excessive use of ionizer can be hazardous. I suggest using the ionizer moderately.

Buying guide – What to know before you purchase the best air purifier under 100?

When you fully convinced to buy a brand-new budget air purifier it’s important to know the different features of it. Let’s find what you should look for when you get an air purifier under 100.

Magnitude of the Filter

The most important aspect of an air purifier is its filter quality. There are various kinds of filters available in the market. The most popular type is the HEPA filter. Other popular types are ion Ionizers and Ozone Generators, active carbon filter, UV lights, washable pre-filters and so on. A specific purifier filter contains 3 to 5 types of the filter plate. Filters catch the unnecessary particles that present in the air. When air passes through the filter, it traps the airborne particles. Some special types of filters can trap bacteria, microbes, and even viruses. When you want to buy an economical air purifier you must keep in mind that a budget purifier may not have a filter that can trap everything.

Extra Expense

Most of the time the filters are not permanent or washable. Therefore, after using a few weeks or months you have to change the filter plate. The frequency of changing the filter plate depends on the performance of your machine and the quality of the atmosphere you belong to. When you want to buy a budget air purifier it’s very important to consider the replacement cost of the filter. Sometimes the main machine will cost lower but after using a certain period it will cost you a lot.

In the market, some purifiers are existent with a permanent filter system, although they are not good for some sensitive environment.

Speed of the Fan

Good quality filters are not the only matter you should keep in mind. The performance of an air purifier largely depends on the fans and their speed. Most of the purifiers have multiple fan speed setting. You can adjust these as per your needs. Sometimes products also come with a speed sensor of the fan that can automatically adjust the speed.

CADR Level

CADR means Clear Air Delivery Rate. The CADR indicates the performance of a purifier. Higher CADR ensures higher operating efficiency. Try to get a purifier with at least 350 CADR or beyond.

Coverage Area

Before you purchase an air purifier, you must measure the area of your room. A purifier with a smaller coverage area can decrease the efficiency remarkably. Generally, devices with larger dimensions cover larger space than the devices having a smaller dimension. Therefore, always keep it in your consideration.


Before deciding on a model you must check the dimension of the appliance. Especially when you purchase it online, check the dimension on and on again. Models that have a larger dimension will cover a larger area but portability may create an issue for you. You need to balance between these two. If you need an air purifier for your car, you are a travel lover who needs to carry the air purifier or the room you need to purify is small then big size models will not be suitable for you.


It’s very important to check the warranty terms for your product. The warranty period simply indicates the trustworthiness of the manufacturer and this is an important quality of any product. A higher warranty period means the producer believes in the performance and durability of the product himself. On the other hand, less warranty period demonstrates that the product might not last long. Before you make the decision, check the terms and conditions with caution as well.

Noise Level

An air purifier is a machine and it contains functional fan in it. Therefore, it usually makes some noise. Generally, the noise level is very low. There might be few models out there that create disgusting sound on higher speed mode. Therefore, before you choose an air purifier, check the decibel range of the model, especially if you have children, pets or sound-sensitive persons in your family.

Smart option

To amplify the efficiency and functionality, manufacturers include some extra options in their products. Most air purifiers of the higher ranges come with various smart options. Nowadays, some budget models also have fewer extra functionality such as filter life indicator, ionizer, light, some kinds of digital functions and so on. But if you have a budget concern, having no smart option is just ok.
