Breathe Easy: A Comprehensive Guide to Air Purifiers


Take a deep breath. Chances are, the air you just breathed in contained many pollutants, allergens, and other particles that can harm your health. Indoor air quality is a concern for many people, particularly those with allergies or respiratory issues. Fortunately, there is a solution that can improve the air you breathe: an air purifier.

Air purifiers or air cleaners are a popular addition to many households, but with many options available, it can be challenging and overwhelming to choose the right one. From HEPA filters to UV-C technology, each one has its own unique features and benefits. In this comprehensive guide, you can take a closer look at all you have to know about such devices, so you can breathe easy and enjoy cleaner and healthier air in your home.

What are the types of air purifiers?


Several types of air purifiers are available, each with its advantages. The most common types are:

HEPA Purifiers: High-Efficiency Particulate Air (HEPA) filters are the most popular type on the market. They are designed to capture particles as tiny as 0.3 microns, making them effective at removing allergens such as pollen, dust, and pet dander from the air. They can be found in both portable and whole-house purifiers.

Activated Carbon Purifiers: They work by absorbing the pollutants as the air passes through them. These air cleaners are less effective at removing allergens than HEPA filters. Still, they can be helpful for people with chemical sensitivities or who live in areas with high levels of pollutants.

UV-C Purifiers: They utilise ultraviolet light to kill bacteria and viruses in the air. These air cleaners are typically used in conjunction with other air purification methods, such as HEPA filters. They are highly effective at killing germs.

Ionic Purifiers: They use ionisation to remove particles from the air. They emit negatively charged ions that attach to positively charged particles in the air. The charged particles then stick to surfaces or are attracted to a positively charged plate inside the device. They can help remove odours from the air.

What are the advantages of air purifiers?

They have become incredibly popular in recent years as people have become aware of the importance of good indoor air quality. There are many advantages to using them in your home, including the following:

Reducing Allergens: Air cleaners are highly effective at removing allergens from the air. It is especially important for people with allergies or asthma, as pollen, dust, and pet dander can trigger symptoms. Removing these allergens from the air can help alleviate symptoms and improve the overall quality of life.

Eliminating Odours: They can also help eliminate odours from your home. It is beneficial if you have pets, smoke indoors, or cook frequently. Activated carbon filters, commonly used in such devices, are excellent at absorbing odours and can help keep your home smelling fresh and clean.

Removing Harmful Chemicals: Indoor air can contain various harmful chemicals, such as volatile organic compounds (VOCs), which can be released from cleaning products, furniture, and other household items. Devices that use activated carbon filters can help remove these chemicals from the air, improving the overall air quality in your home.


Fighting Germs: They can also help fight germs and viruses in the air. Some use UV-C technology to kill bacteria and viruses, while others use ionisation to neutralise germs and other harmful particles. It is especially important during cold and flu season, as it can help prevent the spread of illness.

Improving Sleep: Poor air quality can interfere with sleep, leading to snoring, coughing, and other disruptions. They can help improve air quality, making breathing easier and reducing the likelihood of sleep disturbances. It can lead to better quality sleep and improved overall health.

Improves Cognitive Function: Studies have shown that poor indoor air quality can lead to reduced cognitive function. By improving air quality, they can help improve cognitive function, leading to better focus, memory, and productivity.

What Factors to Consider When Choosing an Air Cleaner?


Choosing the right device can be daunting, with so many different types and models available on the market. However, there are a plethora of factors to consider when choosing one to help ensure you get the most effective and efficient product for your specific needs. Here are some key factors to consider:

Room Size: The size of the room where you plan to use the device is an essential factor to consider. You’ll need one powerful enough to effectively clean the air in the room. If it is too small for the room, it will not be able to effectively remove all of the pollutants and allergens. A general rule of thumb is that you’ll need a cleaner to clean the room’s air at least twice an hour.

Noise Level: The noise level is another critical factor, especially if you plan to use the air cleaner in a bedroom or other quiet space. Some can be quite loud, which can be disruptive to sleep or work. Look for those with a noise level of 60 decibels or less, about the same as a normal conversation.

Energy Efficiency: Air cleaners can use a lot of energy, so choosing an energy-efficient model is essential. Look for those with an Energy Star rating or energy efficiency rating, which means they are designed to use less energy and save you money on your electricity bill.


Maintenance: Maintenance is another essential factor to consider. Some require regular filter changes or cleaning, while others have filters that can be washed or reused. Make sure you choose one with filters that are easy to replace or clean to avoid extra maintenance costs.

Cost: The cost of an air purifier is an essential factor to consider, as prices can vary depending on the model and features. While it might be tempting to go for the cheapest product, it’s necessary to invest in a good quality one that will effectively clean the air in your home. However, that doesn’t mean you have to break the bank. Look for cleaners that offer a good balance of effectiveness and affordability.

Portability: If you plan to move your device from room to room or take it with you on the go, portability is an essential factor to consider. Look for lightweight and easy-moving cleaners with features such as carrying handles or wheels.


Air cleaners are a valuable tool for improving indoor air quality. They remove pollutants and allergens from the air using either filtration or ionisation. Several types are available, each with its advantages. When choosing a device, it is crucial to consider factors such as room size, noise level, energy efficiency, cost, portability, and maintenance. You can enjoy cleaner, healthier air in your home by choosing the right one for your needs.
