Best Air Purifiers Under $100 For Smoke, Dust, Pets, Mold...

germguardian ac4825 mBest Air Purifiers Under $100 are affordable solutions for purifying the air at home and removing harmful particles that can cause asthma, allergies, and other health issues. While vacuum cleaners vacuum floors and other surfaces found at home, air purifiers 'vacuum' the air that one breathes.

Before buying an air purifier, it is important to know what they actually do, how they operate, their features and specifications and in the end, perhaps the most important, why are you buying them ...

Updated: July 21, 2021.

Note: one should not expect these affordable air purifiers to perform like larger and much more expensive air purifiers that cost even 10-20x more. However, they do what they are designed to do.

On this page:


Features and Specifications

There are several important features that determine the quality of air purifiers. Check their specifications and descriptions and try to find the unit that best suits your needs.

Air Flow - air flow is usually given in CFM (Cubic Feet per Minute) or in cubic meters per minute/hour. Stronger air flow means that the air purifier can process and clean more air faster, but it also means that the unit requires more power, often leading to a noisier unit.

Area or Room Size - most air purifiers specify recommended maximum size of the room that the unit is designed for. If the room is larger than that, then the unit might not be able to purify the air as it is declared by the manufacturer.

Operating Noise - noise levels of air purifiers vary significantly from 30 or so dB to 55-60 or even more dB. Passive air purifiers are very quiet units, but their air flow is rather limited. Larger and stronger units tend to be noisy, but fortunately, most of them come with several operating speeds. Higher speeds are intended for use during the day when environment noise is much higher than during the night when so-called 'silent' modes are recommended.

Warranty - warranty conditions are model-dependent, but some models have extra-long warranties (5 years or even more). Although they are low maintenance units, air purifiers are not maintenance-free units - one has to clean or replace filters from time to time and check the general condition of the unit.

Air Filtration Level - level of air filtration is a very important feature for determining the actual quality of the air purifier. Most manufacturers claim that their units are HEPA air purifiers, but they don't always clearly state actual HEPA standards.

The following table lists various classifications of EPA/HEPA/ULPA filters according to the EN 1822 standard:

Filter Group Filter Class Filtration Efficiency Penetration
Efficiency Particulate Air (EPA) Filters E10 85 % 15 %
E11 95 % 5 %
E12 99.5 % 0.5 %
High-Efficiency Particulate Air (HEPA) Filters H13 99.95 % 0.05 %
H14 99.995 % 0.005 %
Ultra-Low Penetration Air (ULPA) Filters U15 99.9995 % 0.0005 %
U16 99.99995 % 0.00005 %
U17 99.999995 % 0.000005 %

hamilton beach air purifier blackNote: In the European Union air filtration is defined by standard EN 1822, which defines several classes of EPA/HEPA/ULPA air filters according to their ability to retain(!) the Most Penetrating Particle Size (MPPS) particles that are in the 0.1 and 0.3 micrometers range.

However, commonly in the US 'true HEPA' air filtration means the ability of the air filter to retain at least 99.97% of 0.3 microns or larger particles. Thus, 'true HEPA' is between H13 and H14 filter classes.

Personally, I prefer when the manufacturer states the exact air filtration ability of not just air purifiers, but vacuum cleaners as well.

Also, it is good to know the size of most common pollutants at homes: bacteria 0.3-10.0 micrometers, pollen 10.0-100.0 micrometers, pet and human hair 30.0-200.0 micrometers, dust mites 90.0-600.0 micrometers, sand 50.0-1000.0 micrometers, etc.

As one can see, it is very important that manufacturers state the size of the retained dirt, too, since some particles can be smaller even than 0.3 microns.

CADR Rating - CADR is short for Clean Air Delivery Rate and is measured by ANSI/AHAM AC-1 standard - air purifier is placed in 1008 cubic feet testing chamber, with the number of air pollutants measured; air purifier operates for 20 minutes at full power and the reduction of air pollutants is measured.

For example, if the air purifier has a CADR rating of 100 for pollen particles, it is able to reduce pollen particle levels to the same level as it would be achieved by adding 100 cubic feet of clean air each minute.

CADR ratings often vary according to the particles filtered, with common values for home air purifiers given in the following list:

- Dust 10 to 400 CADR,

- Pollen 25 to 450 CADR,

- Tobacco Smoke 10 to 450 CADR, etc.

Obviously, air purifiers under $100, especially smaller desk air purifiers, have lower values, while expensive ($1000+) air purifiers have higher values.

CADR also has some limits, too:

- filtration effectiveness of small particles is not shown,

- air purifiers are run at full power, but in real life, they are commonly operated in lower settings,

- decline in effectiveness over time is not shown (filters get dirty over time),

- gas filtration is not measured, which can be very important in removing pet odors and other gaseous pollutants.

There are other drawbacks of CADR ratings, but these are the most important ones.

For example, a solid affordable air purifier can have 100 CFM air flow, HEPA E12 air filtration, and claimed 90+ CADR rating, but in real life, it is able to filter out (retain!) 99.5% of 0.1-0.3 or larger particles (not 99.97%) and perhaps has 90 CADR for pollen, 40 CADR for dust, 25 for tobacco smoke, etc.

For short - read specifications carefully and think about what is particular air purifier offering to you!

Mechanical Filters - mechanical filters are simple, washable pre-filters. They are designed to trap larger particles and extend the life of the other filters (HEPA, activated carbon, etc.)

Activated Carbon Filters - air filters based on activated carbon (charcoal) are used even in gas masks since they are able to remove harmful gases and odors from the air. They should be replaced from time to time, depending on the air purifier usage and the number of pollutants in the air - they can't be washed. For the air purifiers intended for removing pet odors and similar pollutants, they are a 'must have' feature.

Ionic Air Purifiers - ionic air filtration is based on locally generated ions that 'stick' themselves even to the smallest particles, helping the unit to remove those particles from the air flow. Ionic air filtration is commonly combined with good HEPA mechanical filters and even carbon filters for obtaining really high level of air purification.

UV Lamps - UV lamps don't 'filter' air but are used to disinfect air from viruses, bacteria, and other microorganisms that can cause various health issues - UV lamps have a very similar function in mattress vacuum cleaners. Also, UV lamps help keep filters sterile, especially when lifetime filters are used.

There are other features that might be important in certain situations - design, size, weight, power consumption, etc. but their importance often depends on the individual user's preferences and requirements.

2. GermGuardian AC4825 Air Purifier

GermGuardian AC4825 Air Purifier is one of the best affordable air purifiers on the market. And it is also a rather stylish unit that can fit almost anywhere.

germguardian ac4825 2

GermGuardian AC4825 Air Purifier is based on the triple air purification system:

- first layer is based on a mechanical pre-filter with the layer of activated charcoal. This pre-filter retains larger particles of dust, pet hair, and similar debris, while the charcoal layer absorbs household odors (from kitchen and cooking, from pets, smoke, etc.)

5. Hamilton Beach TrueAir Compact Pet Air Purifier - Model 04384

Hamilton Beach TrueAir Air Purifier is a very compact and affordable unit. Its filtering capability might be better, but it comes with a replaceable carbon filter and permanent HEPA air filter.

hamilton beach air purifier 300pxh

Permanent HEPA filter removes 99% of particles - it is 'almost' E12 class air filter. When the filter gets dirty, it is simply vacuumed - for exact maintenance procedures, check the manual that comes with the unit.

Such HEPA filter saves money in the long run, but IMHO 99.97% of retained particles looks so better than 99% of retained particles.

A little bit of math: if you have 10,000 particles in a unit of air, 99.97% filter will remove 9997 particles (3 particles left in the air) and 99% filter will remove 9900 particles (100 particles left in the air).

This 100 vs 3 difference is large, but 10,000 particles (no air purifier at all) vs 100 particles in the air is a HUGE difference. This and other features make this air purifier so popular, even if it is not a 'true HEPA' air purifier.

Hamilton Beach TrueAir Air Purifier, model 04384 comes with two activated carbon air filters - they remove pet odors, odors from cooking, and similar.

The unit has three speeds and is suitable for rooms up to 140 sq feet (~13 sq meters).

Also, it can operate in a vertical position and can be placed horizontally.

Few Final Words

Air purifiers can improve quality of life significantly. Smaller, cheaper units often lack features commonly found on larger, more expensive units, but they do what are they designed to do - they purifier air and remove unwanted air particles and odors like dust, pollen, mold, smoke, etc.

In order to purifier air, a good unit doesn't have to support WiFi connectivity, Amazon Alexa, or Google Home Assistant, there is no need for voice prompts, maintenance reminders, and similar. All those features can come in very handy, but they also increase the price of the units and their complexity.

When considering which air purifier to buy, be aware of its strengths and weaknesses, and choose according to your personal needs and preferences.
