What’s The Difference Between Cheap And Expensive Air Purifiers? Overview

What’s The Difference Between Cheap And Expensive Air Purifiers? Which one is right for you? First and foremost, ask yourself why you want an air purifier. Cheap and expensive air purifiers are different in terms of longevity, filter type, CADR rating, etc. Air purifiers are essential to improve the air quality in your home, especially if you have pets or allergies. There are different types of air purifiers. 

These units are highly functional, but some models cost more than others. Here’s what you need to know about cheap and expensive air purifiers, so you can determine which one is right for your needs and budget. What’s The Difference Between Cheap And Expensive Air Purifiers? Which one is right for you? First and foremost, ask yourself why you want an air purifier. Do you want to clean the air in your home or business because it’s dirty or smelly?

What’s The Difference Between Cheap And Expensive Air Purifiers?

Between different types of air purifiers on the market, choosing which is best for your needs can be challenging. Below, we explain some significant differences between cheap and expensive air purifiers. There are many air purifiers, but the two most common ones are cheap and costly. This post will discuss the difference between these two air purifiers and help you decide which one best fits your needs.  

HEPA filters remove 99.97% of the particles from the air that passes through them. A HEPA filter would be more expensive than one without this efficiency level because it requires more filtration material. Price also increases with size – larger models cost more to manufacture because they need more parts and features to provide the same level of performance as smaller models. More energy-efficient models will also cost more because they have higher-quality pieces that require less energy to run.

Following are some of the Difference Between Cheap And Expensive Air Purifiers:

1: Cheap filters do not last long

What’s The Difference Between Cheap And Expensive Air Purifiers

Cheap air purifiers are typically lower-end models with a more affordable filter. The filters do not last very long and need to be replaced often. This can get expensive over time, and as more dirt and dust accumulate, it becomes more difficult for the filter to clean the air properly. Depending on where you live, there may also be different levels of pollutants in your area that require an even more expensive air purifier with a high-quality filter. While it may be appealing to buy a cheap air purifier because they’re less expensive, in the long run, this will cost you more money because you will have to replace or purchase new filters often.

2: Quality of material used 

Cheaper models generally use filters of a medium-quality material like paper, while more expensive models typically use higher-quality filters like HEPA. Paper filters can be effective in some cases but can also become contaminated with dust particles or other contaminants. Higher-quality filters aren’t a problem because they’re meant to trap these particles before they escape into the air again. 

More expensive models also tend to have replaceable filters, which means you don’t need to replace the whole unit if it’s only been used for a few months. 

That might seem small, but replacing an entire purifier every year can cost around $200. That said, there’s no single answer as to whether cheap or expensive air purifiers are better – both types have their benefits and drawbacks. For example, cheaper models might not offer many features, such as quiet operation and digital controls. On the other hand, cheaper models often come with more extended warranties than their more expensive counterparts, so it may make sense for people who need a lot of coverage.

3:  Ease of maintenance

Generally speaking, cheaper units require more frequent maintenance than more expensive ones. For example, many more affordable units need to be wiped down daily and washed once every week or two. More expensive units may not need regular maintenance – just an occasional vacuum of accumulated dust and debris from the filter itself. Routine maintenance is just an occasional vacuum of accumulated dust and debris from the filter itself. However, this isn’t always the same, and there are plenty of inexpensive units that have longer life cycles with less maintenance required as well. 

Most people should research both options before purchasing your new air purifier to know what kind of service your machine needs.

4: Expensive air purifier filters more surface area 

What’s The Difference Between Cheap And Expensive Air Purifiers

Cheap air purifiers are good, but they will only filter a specific surface area. It’s best to go with an expensive air purifier if you have large rooms or want to filter more surface area. A cheap air purifier should be enough if you only have a small living room. 

Cheap air purifiers might not be as effective at cleaning the air as expensive ones because they usually have one filter instead of multiple filters. An expensive air purifier will remove 99% of particles that are 2 microns in size or larger and up to 99% of particles that are 0.3 microns in size or smaller.

5: Cheap filters are not adequate to remove PM 2.5

HEPA filters are the most effective type of air filter that you can use in your home. HEPA filters can remove 99.97% of particles as small as 2.5 microns from the air, which includes dust, pet dander, mold spores, and other allergens. But not all HEPA filters are created equal, and some cheap models do not provide adequate protection against pollutants that may harm your health. Keep reading to understand what makes a HEPA filter expensive and why you should spend more on a costly model.

Different types of air purifiers

1: Air purifier that uses HEPA filters

2: Air Ionizers

3: UV Air purifiers

4: Electric air purifiers

5: Air purifiers with activated carbon filters

6: Ozone generators

1: Air cleaners that use a HEPA filter

What’s The Difference Between Cheap And Expensive Air Purifiers

Air purifiers that use HEPA filters are better at removing airborne particles because they have a higher efficiency rating. This type of filter will also be helpful if you have allergies or asthma, as it will trap allergens like pollen, dust mites, animal dander, and more from the air. 

 Studies have shown that these particulates can cause breathing problems and trigger allergic reactions, so it’s essential to get them out of your home if you have any respiratory issues. HEPA filters use a combination of activated carbon and gas-charged materials to trap particles before they enter your airways. Most air purifiers that use HEPA filtration are more expensive than non-HEPA models, but they can improve your quality of life if you have allergies or asthma. It’s also worth noting that many filter types will make a quiet humming noise as they run, which might be bothersome depending on where you’re placing them in your home.

2: Air Ionizers

An air ionizer helps you keep your air clean and fresh by using negatively charged ions to remove particles from the air. It creates an electrical field that captures the particles in the mood to create negative ions, which then attach to dust and other pollutants. These particles are either attracted to a nearby oppositely charged plate or pulled into a filter where they collect and can be removed from the air. 

Air ionizers work well with allergies, asthma, and respiratory problems because they reduce airborne irritants. They also provide comfort because they have been shown to produce negative ions that have calming effects on people who suffer from seasonal affective disorder (SAD) or mood disorders like depression.

3: UV Air purifiers

UV air purifiers, also known as Ozonators, use UV light to break down particles in the air. This technique can be used on various contaminants but won’t work on chemical vapors or gases. UV air purifiers are good at cleaning large areas because they use the Ultraviolet Germicidal Irradiation process that destroys all microorganisms in the area. They work by emitting ultraviolet light to kill bacteria and viruses.

It’s important to note that this cleaner has been known to cause eye damage if you look directly at it for too long. It’s recommended not to leave children unattended near these devices. Also, UV lights may wear out over time so if you want a more permanent solution, consider getting an air cleaner with a scrubber component like carbon filtration or an ionizer component that uses electrostatic attraction to pull particulates from the air before they get broken up into smaller pieces. 

4: Electric air purifiers

What’s The Difference Between Cheap And Expensive Air Purifiers

However, many people who cannot afford more expensive models will purchase and use an electric air purifier. These devices have a filter that traps pollutants in the air and releases clean air into the room. They are very effective at trapping dust particles from carpets, upholstery, and other materials in your home.

An electric air purifier may not be as powerful as some of the other options on this list, but it can still provide significant benefits to those with allergies or asthma.  So if you’re looking for an affordable option that still offers a decent amount of filtration power, an electric air purifier might be a good choice.

5: Air purifiers with activated carbon filters

Air purifiers with activated carbon filters are great at removing chemical odors and smoke from the air. This type of filter usually needs to be replaced every six months. It also removes formaldehyde, paints, pesticides, and other volatile organic compounds (VOCs) from the air. These filters can get rid of a lot of dust as well. If you want to remove pollen, molds, bacteria, and pet dander, you will also need an allergen-specific or HEPA filter. Allergen-specific filters include HepaAllergy and HepaPet. All these air purifiers work wonders in reducing indoor allergens and pollutants from the home environment.

6: Ozone generators

Ozone generators are air purifiers that use ozone gas to clean the air. An electric discharge generates ozone gas in a high-voltage field, which causes oxygen and other atmospheric gases to react. Ozone generators can effectively remove odors, bacteria, fungi, and viruses from the air. An ozone generator can be either cheap or expensive, depending on its features and size. A smaller unit might cost less than $200, while a larger one could go for more than $1,000.

Should you buy an expensive or cheap air purifier?

The short answer to purchasing an expensive or cheap air purifier depends on your needs.

Here are some considerations to follow:

1: Room size

2: Type of pollutants

3: Health problems

4: Feature

1: Room size

The room size determines how much air needs to be purified at once. In small spaces, a cheap air purifier might work fine. However, an expensive air purifier may be necessary if you have an ample living room with high ceilings and lots of carpets. You also need to consider how many people are in your home and what kind of allergies they have. Some people have dust mites or pollen allergies, so these might need to be considered when choosing the best air purifier for your household. 

2: Type of pollutants

Cheap air purifiers can work well to remove indoor pollutants such as cigarette smoke, pollen, mold spores, household dust, and pet dander. They are less expensive to buy and maintain than their more powerful counterparts.

Expensive air purifiers use higher-grade filters that trap a more comprehensive range of pollutants, including gases like formaldehyde and VOCs (volatile organic compounds) from paints and solvents found in furniture or building materials. These types of cleaners also may have additional features, such as a UV light that kills viruses and bacteria.

3: Health problems

We stay most of the time in our homes, and as a result, they can become home to all sorts of pollutants. This includes dust, pollen, dander, smoke particles, mold spores, and more. These pollutants often come from outside and enter the air inside your home through doors and windows or seep through your vents when you use your heater or air conditioner. Pets also contribute to the problem with their dander floating around the room on their fur. Even if you’re not allergic to these things, it’s still not good for your health to constantly breathe them in.

4: Feature

Are you looking to buy an air purifier but not sure what the difference is between cheap and expensive ones? There are a number of differences between these two, so let’s look at them. 

Cheap cleaners use a pre-filter that catches larger particles from the air before it goes into the primary filter. This can save you some money because it doesn’t use as much of the more expensive HEPA filter. 

Expensive air purifiers use pre-filters and HEPA filters to remove smaller particles from the air. They also offer features like UV lights or ionizers, which don’t come with cheaper models. These features give your home cleaner air without creating any additional pollutants. You will also find a better warranty on high-end models than on more affordable brands, which is essential if you have allergies or breathing problems in your home. 

So when choosing between expensive and cheap air purifiers, there isn’t just one answer that fits everyone’s needs. In general, though, we recommend going with an inexpensive model if you have only occasional allergies or asthma flare-ups and go with the expensive model if you need something reliable 24/7 for your child who has asthma or allergies or has pets in their bedroom, like cats or dogs.

Cheap vs expensive air purifiers which one is right

What’s The Difference Between Cheap And Expensive Air Purifiers

HEPA filters are the best choice to ensure that your air purifier can remove allergens and irritants from the air. HEPA filters are not cheap, but with proper maintenance, they will last a long time. 

Cheaper air purifiers rely on electrostatic plates and ionizing technologies to clean the air. These methods don’t work as well as HEPA filters and won’t be nearly as efficient in removing allergens and irritants. HEPA filter-based air purifiers have pre-filters and post-filters. Pre-filters capture larger particles, like dust, dirt, and pet hair, before entering the machine’s exhaust filter. Post-filters help maintains a cleaner environment inside the machine by capturing smaller particles that manage to escape through the exhaust filter. 

The key word here is PREVENTION because it helps avoid costly replacement of both pre-and post-filters more often than usual.

FAQs: What’s The Difference Between Cheap And Expensive Air Purifiers

There are many different air purifiers and other factors to consider when choosing the best air purifier for your home. We’ve listed a few common questions below to help you make an informed decision.

What type of filter does my air purifier use? 

There are two main types of filters, HEPA (high-efficiency particulate arrestance) and charcoal. HEPA filters can remove 99% of particles that are 0.3 microns or larger from the air, and charcoal filters reduce odors by attracting them to their surface. HEPA filters can be more expensive than charcoal, but they generally work better at removing allergens like dust, pollen, and pet dander from your home’s atmosphere.

How can I determine what type of filter I need to buy?

HEPA filters are a type of high-efficiency particulate air (HEPA) filter designed to capture large airborne particles and gaseous pollutants with a tiny fraction of the air volume. They are used in many products, such as vacuum cleaners, air purifiers, and industry. HEPA filters have been tested to remove at least 99.97% of airborne particles that measure 0.3 micrometers or larger in diameter, including dust mites and pet dander. This makes them an excellent choice when you need to remove allergens from your home or workplace environment. 

HEPA filters should be replaced every two years under regular use to maintain effectiveness and efficiency.

Which type of air purifier is best for COVID19? 

Many air purifiers use HEPA filters to help remove COVID19 from the air. 

The cheapest type of air purifier will likely have an activated carbon filter to reduce odors and an electrostatic filter to reduce airborne particles. Still, it won’t have a HEPA filter, so it can’t remove COVID19 from the air. The most expensive type of air purifier has a HEPA filter and removes COVID19 from the air by trapping them in its fibers and destroying them before they get released into the atmosphere.

Does an Activated carbon filter remove VOCs?

Activated carbon filters can remove some VOCs, but they’re not always effective against many chemicals. For example, they might be unable to remove formaldehyde or benzene from your home. It’s important to know what type of contaminants you need to remove and what filters are best suited for those contaminants before you purchase your air purifier. If you’re concerned about VOCs, consider an air purifier that uses either the HEPA filter or a combination HEPA/activated carbon filter.


Selection of the right air purifier can be challenging. There are many different types of air purifiers available on the market, each with pros and cons. I would recommend starting by reading reviews of other people who have purchased the same product. This will give you a good idea of what to expect when purchasing an air purifier. 

Remember that most positive reviews likely come from people who are satisfied with the product and don’t need to rely on it as much as someone suffering from allergies or asthma might. It’s also essential to consider how ample your living space is before purchasing a particular model, as well as any allergies or sensitivities you may have.

If you’re unsure which model to choose, start with a more affordable option like the Honeywell HPA300 and see if it helps. If not, consider upgrading to the Honeywell HPA500 or Philips AC4300, depending on your needs and budget.
