HEPA filters are ideal for those who suffer from allergies and asthma as they are specially created to trap even the smallest microbes and harmful pollutants in the air.
They work with the purifier to clean the air and create a more breathable environment for the sufferer to be in.
However, they also work with the purifier to remove bacteria, viruses, and fungi from the air, and can work fantastically when it comes to helping pet allergies as well as mould.

Key Things To Look for
Before you go and buy your new air purifier, there are a few things that you need to take into consideration. The information below will help you to make a clearer and more informed choice about the model you pick up and also with regards to what you need in your home.
Coverage Area. How large an area do you need your air purifier to cover? Is it going to sit in a small bedroom, or will you be using it in a large living area?
Every air purifier has its own set of restrictions with regards to the area in your home that it can cover. Always check what room size it is suitable for, as well as the square footage where possible.
Filtration Types. The filter is responsible for capturing particles and allergens in the air so that only clean air is pushed back out into the room. There are several types of filter available for air purifiers, the most popular of which is the HEPA filter.
These filters are capable of capturing particles as small as 0.03 microns, which means that pretty much every allergen is covered. They are the best and most effective filter. You will often find them combined with carbon filters.
These are especially useful for odour removal, and they are brilliant if you are a smoker. They are effective with pretty much any organic compound, making them a perfect partner for HEPA filters. UV lights are also becoming a popular type of filter.
These are highly effective and are even capable of removing viruses from the home. They kill germs and mould to make your home safer and the air cleaner than ever. Finally, you have ion and ozone filters. These are the least desirable, however, because they can trigger asthma.
Those with respiratory issues should avoid these filters because the ozone in the air can irritate the lungs quite easily. They work in a similar way to electrostatic filters (which can also produce ozone) in that they give particles a charge that causes them to stick to the filter instead of float.
Filter Life. You want your filter to last a little while before it needs to be replaced. However, this will also depend on how much grime is in the air and needs to be captured.
On average, a filter can last anywhere from six months to a year, but there have been extreme cases where it has needed to be changed after a month when brought into a new home.
The best thing to do with filters is to buy a good quality one that will last you at least six months. Following this, it should be checked monthly just to see how clean it is and so that you can roughly guess how much longer it will last.
Particle Removal Capacity. You want your air purifier to be able to remove as many particles from the air as possible. Now, these particles come in a range of sizes and not all filters are equipped to handle the small ones.
This is why the HEPA filter is such a good choice, and it is able to capture particles as small as 0.03 microns. What this means is that it can capture 99.97% of all particles in the air. That’s an impressively high number, and also the reason why people don’t usually pick anything other than HEPA.
Portable & Ease of Use. If you have a big bulky air purifier then it’s going to be difficult to move around or swap rooms.
Pick an air purifier that’s lightweight and easy to move, but also one that has simple controls so that you can just switch it on and leave it to do its thing. The last thing you want is to be stuck with a machine that is not only confusing but also impossible to move.
Noise Levels. Air purifiers can be incredibly noisy, and you want something that hums quietly in the background so that you barely notice it.
This is especially true if the purifier is located in your bedroom. Pick something that has a low decibel reading. 25dB tends to be near-silent, and anything that goes above 50-60dB you will not be able to sleep near.
Warranty. You want your air purifier to be covered in case anything happens to it, and most manufacturers will supply you with one that lasts at least one year after purchase. Many will allow you to extend this to five years if you register it online.
Check that it covers things like malfunctions and repairs, and also that parts and labour are included in the terms of the warranty. You can also look out for a guarantee, but this isn’t as extensive and cannot be extended as a warranty can.
Frequently Asked Questions
Are air purifiers safe and healthy machines to run in my home?
Yes, air purifiers are safe and healthy machines to run in your home. They shouldn’t cause any adverse health issues and are completely safe to have around people and animals.
Of course, those with respiratory issues and children should try to avoid the models with ozone filters, but this is very easy to do.
Do air purifiers give off radiation?
Yes, air purifiers do give off radiation. However, this isn’t something you should be concerned about. They produce a small and safe amount of EMF (electromagnetic field) radiation, just like your microwave or mobile phone.
These are harmless quantities and no scientific studies have shown them to be dangerous in any way.
Should you run your air purifier all the time?
Yes, you should run your air purifier all the time. You cannot run it for a few hours a day and expect the air to be left clean at all times after.
This machine is working hard to purify the air in your home, and so you should leave it running at all times. If you are concerned, you can lower the fan speed to keep it ticking over and cleaning while you are out or sleeping.
How long does it take an air purifier to clean a room?
It takes between 30 minutes and two hours for an air purifier to clean a room. This is largely reliant on the size of the room in question and the number of pollutants in the air.
However, just because it has finished after this time doesn’t mean you can turn it off. Pollutants are constantly entering the air in your home and so the air purifier is always working to keep the air clean.
Where is the best place to put an air purifier in a room?
The best place to put an air purifier in a room is near walls, doorways, or even the side of the fridge. This actually enhances its ability to clean the air and cycle clean air back into the room.
In the bedroom, it should be at least six feet away from the head of your bed, preventing a draught and allowing you to obtain the full benefits of air purification.
Do air purifiers help sinus problems?
Yes, air purifiers do help sinus problems. Dust, pollen, and other common allergens can cause sinus issues, and an air purifier works by removing these from the air to make it more breathable.
Combined with eating well and getting exercise every day, an air purifier can massively relieve your sinus issues.
What are the main differences between cheap and expensive brands?
The main difference between a cheap and expensive brand of air purifier is the purification process and the filtration system. More costly models will often have an advanced system, and the filters will be HEPA grade, if not HEPA Plus or UV.
The expensive models are often quieter, have a better filter life, and come with additional features to improve usability.
Of course, spending more does not guarantee an amazing model. Sometimes, the budget ones perform better than high-end ones. Pay attention to the reviews.
A HEPA air purifier is great for those who need something powerful to clear odours and pollutants from the air. With a great range of brands and models available to choose from, you are sure to find something here that is perfectly suited to your home.
Whether you need a large model to clear your room, or something a little smaller and more compact, there is an option here for you.
With these reviews, the decision making process should be that much easier and you are sure to find the best HEPA air purifier for allergies.
