Inexpensive Air Purifiers: Buying Guide

Why Buy a Budget Air Purifier Over and an Expensive One?

Air purifiers are quite expensive and can prove to be quite a burden on your pocket. However, some inexpensive options are also available that are in no way less in performance and effectiveness compared to the expensive models.

You need to keep in mind the differences between a budget and an expensive air purifier when choosing a model:

Room Coverage

best cheap air purifier

Most inexpensive air purifiers can only cover a room of around 80-200 sq. ft. On the other hand, air purifiers that can cover a larger area tend to be pricier.

If you are looking for an air purifier for a small office, living room, or small bedroom, investing in a cheap model is the best choice. Purchasing an expensive unit that can cover up to 500 sq. ft for a small room is not recommended.

Types of Filter

In order to manufacture inexpensive air purifiers, a number of manufacturers design their models with a single-stage air purifying process. Such devices are economical but not as effective as expensive ones.

A single-stage air purifier has only one type of filter and can purify the air from a small number of toxins. Hence, such an air purifier is capable of removing particles that cause bacteria; fine dust, or odors, but not all three. This is why you need a multi-stage air purifier and not a single-stage one.

A multi-stage air purifier provides the best value for money as it combines several types of filters to provide protection against a number of harmful airborne particles.

The several multi-stage filter options include:

  • HEPA filter: This filter is highly effective in pulling in and trapping microscopic allergens such as mold spores; pet dander, pollen, and fine dust.
  • Pre-filter: This filter collects big particles such as large dust and hair and helps to increase the life of other filters in the air purifier.
  • Activated carbon filter: Efficiently removes household odors, airborne chemicals, and smoke.
  • UV light: Kills airborne viruses and bacteria and provides a sterile environment.
  • Ionizer: Excellent at neutralizing the various particles present in the open-air space;thus making them easier to catch in the HEPA filter.

Most inexpensive models feature good-quality filters such as HEPA-type or HEPA-grade. However, this filter is not as efficient as a true HEPA filter.

Hence, if you suffer from asthma or severe allergies, an inexpensive air purifier may not be enough for you. On the other hand, it is better to choose a cheap air purifier if you just want to improve your surrounding air.  

Frequency of Filter Change

The frequency of filter replacement generally depends on its size and not it’s quality. Some inexpensive models claim that their filters can last for almost six months. However, it is best to read customer reviews before choosing a model to find out about their experience.

What to Look for When Buying a Low-Cost Air Purifier

best inexpensive air purifier

New developments in the world of air purifiers have enabled consumers to enjoy the best performance at an affordable price. However, if you are worried about finding a low-priced unit that functions exceptionally well, it is vital that you keep the following features in mind.

Area Coverage

The first thing to consider when looking for an air purifier is the size of the room it can efficiently cover. Typically, inexpensive air purifiers are designed to handle small spaces. This low power is the major contributing factor to their affordability.

However, this should not serve as a deterrent for buying one. Even though you are searching for an inexpensive model, you should look for one that will be suitable for your room size.

All air purifiers are equipped with a square footage area coverage rating. Make sure that the model you choose comes with a rating that is perfect for your specific needs.

To find the suitable air purifier size, just measure the square footage by multiplying the length and width of the room where you want to place the air purifier unit. Then ensure that the air purifier you choose meets this size requirement. 

Efficiency

ACH or the air purifier’s air change per hour refers to the number of times a purifier can filter the whole volume of air per hour in the treatment area. People who suffer from asthma or have allergies should look for a model that can clean the air in the room at least four times an hour.

In addition, a rate of four air changes every hour ensures air that is thoroughly clean and free from a large number of microscopic symptom-triggering allergens to help you breathe easier.

Air purifiers come with various certifications. Before buying a unit, it is best to look for them on the packaging. The different certifications include:

Energy Star Logo – Air purifiers work round-the-clock to ensure clean air in your home or office, and you should consider their energy cost when you choose a model. Purifiers that are Energy Star certified are 40% more energy-efficient compared to standard models. 

AHAM Verified seal – A product that carries the AHAM Verified seal indicates that it has been tested by the Association of Home Appliance Manufacturers. This guarantees that the product is safe to use.

Portability

Some air purifiers are more mobile and lighter than others, which makes them easier to move from one room to another. Moreover, you can keep smaller units on a shelf or a desk. The heavier and larger air purifier units are best kept stationary, although some might feature casters for easy portability.

If you want to use one unit for the whole home, it is best to choose a smaller device or one that you can easily move.

Cleaning and Maintenance

best budget air purifier

Regular cleaning is important for the efficient performance of your air purifier. Moreover, its maintenance requires a certain amount of effort and cost in order to get the best out of your air purifier.

You need to replace the filters at intervals recommended by the manufacturer or as needed, depending on the level of pollution inside the room.    

These filter replacement costs vary from unit to unit. Some models are designed with expensive filters that can last for many years, while cheap filters require frequent change. Moreover, some pre-filters can be washedwhile the HEPA filters are disposable and need to be replaced completely.

Before choosing an air purifier, calculate the cost per annum to maintain it and compare it with other devices so that you can find an efficient unit without compromising on your budget. 

Filter Replacement Frequency

best low cost air purifier

Filters in air purifiers determine how effectively they can purify the air in your home. And because the air is continuously passed through them, it is important to clean or change them regularly.

Choosing a model with an expensive filter can cause them to become costlier compared to the price of the product itself.

Moreover, some air purifier models need filter replacement every 1-3 months, which can really cause the expense to add up. Always check the specifications and details provided to get complete information about the product.

Build and Durability

An air purifier is quite an investment. Therefore, it is essential to choose a manufacturer known for its good reputation and top-quality products. Make sure that the unit is durable and will provide you with long service life.

Operational Cost

Air purifiers, like all other home appliances, need electrical energy to operate. Since these devices need to run continuously, it is better to consider the amount of energy a model uses before buying it.

Different air purifiers use varying amounts of power, typically between 5-200W, depending on their fan speed.

Small air purifiers use less energy compared to larger ones, but they are more suitable for smaller spaces. Air purifiers designed for large rooms have a higher fan speed, and they tend to draw more energy.

Moreover, it is best to choose a device that carries the Energy Star certification as it will use the least amount of energy and will be the cheapest to operate.  

Noise Levels

inexpensive air purifiers

You do not only need to take the performance of an air purifier into account but also ascertain how well you will be able to live with it. An air purifier needs to run constantly which is why it should have a quiet operation.

For instance, a noise rating of around 50dB is almost equal to that of a refrigerator. The decibels of a model are typically printed on the packaging or can be found on the manufacturer’s website. Make sure you choose a quieter model, one that does not interfere with your work or sleep.   

Frequently Asked Questions

best inexpensive air purifiers

If I run the air purifier all day, how much can it cost?

Most HEPA air purifiers use about 50-100W per hour. However, this depends greatly on the airflow speed. Typically, an air purifier that runs all the time will cost anywhere from 0.05-$1.00 per day. That is approximately 0.35-$7.00 per week. 

Are there any efficient air purifier under $100?

There are a number of inexpensive models in the market that deliver reliable and quality filtration. However, it may take some research to find one.

Most air purifiers are costly, but you can find some high-performing models that cost less than $100. Moreover, some effective units cost even less than $50.

These units may be smaller in size but can get the job done effectively. Despite the common belief that cheap products do not perform well, these budget air purifiers are designed with a true HEPA air purifier that offers almost 99% efficiency in eliminating airborne allergens such as pollen and dust mites. 

Why are air purifiers expensive?

The high price of air purifiers is due to a combination of components, product features, and marketing. Improved technology, smart features, effective marketing, and newer components are all the major reasons that make these devices so expensive.
