Affordable Air Purifier: A Brief Buying Guide

When shopping for an air purifier, there are two major factors that will affect your purchase decision. Let’s briefly go over what those two factors are.

Room Size

The most important part of determining which air purifier to get is room size, or in other words, the device’s maximum coverage capacity. While you can find inexpensive air purifiers almost anywhere, the last thing you want is to purchase a model that can reach all four corners of your bedroom, home office unit, etc.

Simply put, affordable air purifiers are smaller appliances that come with smaller motors and fans. So, before settling on a model, make sure that the air purifier is equipped to purify the air in the room you wish to clean.

To do this, multiply the length and width of a room, then take that figure and compare it to the maximum area cleaning area. If the coverage area is larger than the area of a room, then it shouldn’t have any trouble purifying the air.

Affordable air purifiers typically come in two varieties—desktop and free-standing. Desktop models take up very little space, but their compact designs mean a shorter cleaning range.

Free-standing or floor air purifiers are exactly what you would expect an air purifier to look like. They’re medium-sized appliances that rest in the corners of rooms that draw in large quantities.

The third not-so-common design among low-cost air purifiers is hanging models. They’re mounted on a flat, vertical surface, so they don’t take up any floor or tabletop space.

Each design has its own set of advantages and disadvantages, but if you want to get the biggest bang for your buck (in terms of performance and features), you should consider getting a free-standing air purifier.

According to a study done by the World Bank and Institute for Health Metrics and Evaluation (IHME), “air pollution is the fourth-largest threat to human health, behind high blood pressure, dietary risks, and smoking.”

Noise Levels

Modern-day devices are generally whisper-quiet. They produce anywhere from 32 to 77 dBa at any moment, depending on which fan speed is active.

Please note that an air purifier with lower noise levels is generally “weaker” than its louder counterparts. Again, your purchase decision should depend on the size of the room you wish to purify. Larger rooms require noisier air purifiers, in a general sense.

Additional Features to Look for in an Affordable Air Purifier

Here, we’ll go over the features and specs you should keep an eye out for when shopping for in an affordable air purifier.

Clean air delivery rate (CADR) and air changes per hour (ACH) are two figures that will give you a clear idea of how well an air purifier performs.

Regardless of the price bracket, you should try and find an air purifier with the highest CADR figure relative to its size. For instance, a free-standing model that delivers at least 200 CFM (cubic feet per minute) in all three CADR categories (dust, pollen, and smoke) denotes better, more efficient purifying performance.

As for ACH, you can do the math by calculating the volume of your room and dividing it by the maximum CFM output of your air purifier. For instance, if your living room is 15 x 20 x 8 feet (2,400 cubic feet), and your air purifier has a CFM rating of 250 CFM, then it can produce around 10 ACH (2,400/250 = ~10).

Single vs. Multi-Stage

Apart from the CADR and ACH figures, you should take a good hard look at the number of filters the device comes with.

A single-stage air purifier is an air purifier with a single filter inside, whereas a multi-stage air purifier contains at least two filters. The more filters the appliance uses, the better it can clean the air.

Let’s take a look at the types of filters down below:

  1. Pre-Filter: the first line of defense that traps a majority of large-sized particles, preventing them from clogging subsequent filters.
  2. Standard Filter: a simple filter typically made of a spongy material that’s washable but not completely reliable in removing microscopic particles
  3. True HEPA Filter: the best kind of filter you can get. They have the ability to retain particles as small as 0.3 microns with 99.97% efficiency.
  4. Activated Carbon Filter: typically the last line of defense, this type of filter removes foul smells in the air by absorbing and neutralizing odor molecules.

Optional Filters

An optional filter is a type of filter that you can turn on and off at will. There are two kinds of optional features you can get in your air purifier. Here’s a brief description of what they are.

  1. UV Light: a dedicated “kill chamber” within the appliance that exposes microorganisms to UV-C light, effectively destroying them at the molecular level. If the microorganisms don’t die, at the very least, they can’t reproduce.
  2. Ionizer: ionizers deliver a static charge to airborne particles, forcing them to adhere to the filters for enhanced cleaning performance.

Please note that both types of optional filters can produce ozone—a lung irritant—though some brands claim their UV-C and/or ionizer filters do not. To be on the safe side, only run these optional filters when no person or pet is present indoors and allow for several hours for the ozone to dissipate before re-entering your home.

Did you Know

That rental homes, mobile homes and homes located in rural areas are more likely to have elevated levels of indoor allergens.

Filter Lifespan and Replacement Indicator

How long a filter lasts—i.e., can maintain optimal purifying performance—will vary from model to model. In general, True HEPA Filters, even washable ones, have a maximum lifespan of between 6 and 12 months, though it depends on how frequently you use the air purifier.

You can manually count how many months have passed before purchasing replacement filters, or you can rely on an LED replacement indicator to warn you when the filter is nearing the end of its lifespan. They’re not always accurate, especially in affordable air purifiers, but it’s safer to replace a filter before rather than after it is no longer effective.

Smart Sensors

Smart sensors can go by a variety of different names, depending on the air purifier manufacturer. A smart sensor is a sensor built into the air purifier that constantly measures pollution concentration levels in the room.

After pollution levels reach a certain threshold, the air purifier will automatically turn on at the most appropriate, energy-saving fan speed.
You’ll mainly find this is premium air purifiers, though some brands offer air purifiers with handy smart sensors at a bargain.

FAQs About Affordable Air Purifiers

1. How much power does an affordable air purifier use?

Affordable price tags typically use very little energy per hour. The average range is between 20 and 100 watts per hour, which equates to about 1.3¢ per hour.

Multiply that by however many hours you run it per day, multiply that by 365, and you’ll have a rough idea of how much more you’ll have to pay to power your air purifier.

2. How long should I run my air purifier?

There’s no hard minimum or maximum hour-per-day figure you can rely on. You can simply follow your nose (and allergies) to determine whether you should leave it on or shut it off. Or you can simply let your smart sensor do all the calculating for you.

A good rule of thumb is to let your air purifier run for at least 12 hours daily.

3. What are the disadvantages of an affordable air purifier?

The disadvantages of an air purifier, affordable or otherwise, vary from model to model. A lack of features and excessive maintenance are two examples of why several affordable air purifier models didn’t make our list.

Also, keep a close eye on how frequently and how long you allow the ionizer and UV-C light (if available) to run.

4. Where can I keep my air purifier?

The design and style of your air purifier will tell you where you can place it, as well as the paperwork. Desktop air purifiers should be on top of a flat surface to promote the best inward airflow possible.

Floor models can be placed in a corner with their exhausts facing upward or uncovered to the back. As for cylindrical models, you can place them virtually anywhere you like.


And there we have it, ladies and gentlemen—our top picks and guide on how to buy an affordable air purifier.
