Why You Should Buy An Air Purifier For Your Home


At home, I’ve had dehumidifiers and I have had a small air purifier just for my office. I wanted to remove dust particles from the room to give me better air quality. This was only a small air purifier and so only did small spaces.

However, with summer coming up soon I decided to invest in a larger air purifier that can clear larger rooms, maybe even the entire floor space. Reason why I will explain below.

This post is based on my own experience of purchasing and using an air purifier. The one I currently have is the Shark Air Purifier 4 US Link Or for UK Shark Air Purifier 4.

What Is An Air Purifier?

What is an air purifier? It is a device that removes contaminants from the air. These devices use various techniques and methods to clean the air. The most common method is by passing air through a filter that captures dust, bacteria, pollen, animal dander, etc.

An air purifier works by pulling air through a filter or series of filters that trap and remove particles like dust, pollen, smoke, pet dander, and other airborne allergens.

Air purifiers can use various types of filters, including HEPA (high-efficiency particulate air) filters, activated carbon filters, and UV-C light technology, to remove different types of pollutants from the air. Some air purifiers may also use ionizers to charge particles and make them easier to capture by the filters.

All air purifiers I have used in the past use a filter such as a HEPA filter. They suck in air and have 1 or more vents in which the clean air is blown out. I also find that this air is cooled down giving the room a cooler feel around the unit.

Air purifiers are commonly used in homes, offices, and other indoor spaces to improve air quality and create a healthier living environment. They can be particularly useful for people with allergies or respiratory issues, as they help to remove airborne allergens and irritants that can trigger symptoms.

Why Buy an Air Purifier?

Air purifiers can provide several benefits for your home environment, including:

  1. Improved Air Quality: Air purifiers can help remove pollutants such as dust, smoke, pollen, pet dander, and other allergens from the air, improving the air quality in your home. This can be particularly beneficial for people with allergies or respiratory issues.
  2. Reduced Odors: Air purifiers can also help reduce odors in your home, such as those caused by cooking, pets, or smoking.
  3. Better Sleep: By improving the air quality in your bedroom, an air purifier can help you get a better night’s sleep by reducing the number of allergens and pollutants in the air.
  4. Improved Mood: Cleaner air can lead to an improved mood and less stress, which can have a positive impact on your overall health and well-being.
  5. Reduced Asthma and Allergy Symptoms: An air purifier can help reduce the symptoms of asthma and allergies by removing allergens from the air, making it easier for people with these conditions to breathe.

Overall, an air purifier can help create a cleaner, healthier, and more comfortable living environment for you and your family.

My main reason for purchasing is due to hay fever. I hope that an air purifier will make my summer more enjoyable when indoors, helping to remove pollen and dust to help me sneeze less.

How an Air Purifier Works

Air purifiers work using a simple concept. They suck in air and pass it through a filter and then blow the cleaner air out. Of course, this is a simplistic view and explanation. The technology used in air purifiers ranges from ionization to ultraviolet light and they all use a common method of cleaning the air.

Air purifiers work by removing pollutants and contaminants from indoor air. The exact process varies depending on the type of air purifier, but most air purifiers work in one or more of the following ways:

  1. Filtration: Many air purifiers use a filter, typically a HEPA (High-Efficiency Particulate Air) filter, to capture particles like dust, pollen, and pet dander as air is pulled through the device. HEPA filters can trap particles as small as 0.3 microns with an efficiency of 99.97%.
  2. Activated Carbon Adsorption: Some air purifiers use activated carbon filters to remove odors and gases from the air, such as those caused by cooking, pets, or smoking. Activated carbon filters work by adsorbing (not absorbing) the gases and odors to the carbon material.
  3. Ultraviolet (UV-C) Light: Certain air purifiers use UV-C light to kill bacteria and viruses in the air by damaging their DNA, preventing them from reproducing.
  4. Ionization: Air purifiers that use ionization charge particles in the air, making them more easily captured by filters. Negative ionizers attach negative ions to particles, and positive ionizers attach positive ions to particles. These particles are then attracted to oppositely charged surfaces, such as walls or filters.

Some air purifiers use a combination of these methods to maximize their effectiveness in removing pollutants from the air.

What to Look For in an Air Purifier

With all this being said, what should you look for in an air purifier?

  1. Room size: To start with, make sure it has adequate capacity to handle your space. Make sure to choose an air purifier that is appropriate for the size of the room where you plan to use it. Check the manufacturer’s specifications to ensure that the unit can effectively clean the air in the room.
  2. Ease of use: Ease of use is important. It’s not really good having a tool such as an air purifier if you don’t know how to use it. You need to understand how to set it up, how to use the modes, and how to clean and replace the filter(s). You need to check whether the air purifier is equipped with a good user manual so you will be able to make sense of the instructions. Also, make sure that the machine comes with a good warranty and maintenance service plan.
  3. Filter type: Consider the type of filter used in the air purifier. HEPA filters are generally considered the most effective at removing airborne particles, but other types of filters, such as activated carbon filters, may be useful for removing odors and gases.
  4. Noise level: Look for an air purifier with a noise level that is comfortable for your environment. Some air purifiers can be loud, especially at higher fan speeds.
  5. Energy efficiency: Look for an air purifier with an Energy Star certification or one that is energy-efficient to minimize energy usage and costs.
  6. Maintenance requirements: Check the maintenance requirements of the air purifier, such as how often the filter needs to be replaced and how easy it is to clean the unit.
  7. Additional features: Consider additional features such as programmable settings, air quality sensors, and remote controls.
  8. Brand reputation: Look for air purifiers from reputable brands with positive customer reviews and good warranties to ensure that you are getting a quality product.

Ultimately you need to consider your needs and preferences when choosing an air purifier to ensure that it is effective and suitable for your specific situation.


In conclusion, buying an air purifier can provide several benefits for your indoor environment, including improved air quality, reduced odors, better sleep, improved mood, and reduced asthma and allergy symptoms.

An air purifier can help remove pollutants and allergens from the air (pollen is my main concern), making it a healthier and more comfortable living space for you and your family.

When choosing an air purifier, it’s important to consider factors such as room size, ease of use, filter type, noise level, energy efficiency, maintenance requirements, and additional features.

By selecting an air purifier that meets your needs and preferences, you can create a cleaner, healthier, and more comfortable living environment.

Choosing an air purifier can seem like a daunting task. There are so many different air purifier types, models, features, and specs that it’s easy to get overwhelmed. Just remember that when choosing an air purifier, there are several important factors to consider, such as the size, price, operating system, filtration method, filter life, and noise level and choose the one that meets your needs.
