Are Bladeless Fans Better For Allergies? (do they purify the air)
Due to their design, all bladeless fans reduce the amount of dust that’s flowing through the air. This is because the blades are inside the fan behind a fine grill that prevents some dust particles from entering the system.
However, there are many allergy sufferers that get problems with the smaller particles like pollen and dust mites.
If you want a bladeless fan that is guaranteed to remove allergens from the air, you’ll need to buy one that has a HEPA filter.
Bladeless Fans With HEPA Filters
Although Dyson are the brand leaders, there are several other companies that now produce bladeless fans and some of these also contain a HEPA filter to remove fine dust and pollen particles.
A decent HEPA filter will trap 99.95% of all particles as small as 0.1 microns and will need to be replaced once a year. On some models there’s an LCD display screen that notifies you when the filter needs changing.
What Is HEPA? (what does it mean)?
HEPA is an acronym for High Efficiency Particulate Air (filter) and is made using thin fibres of glass and activated carbon based materials
While regular filters are made from cotton, paper or polyester which are porous and allow fine particles through, HEPA filters can trap very fine particles as small as 0.1 micron.
A micron measures at just one twenty-five thousandth of an inch or one millionth of a metre.
To give you some idea of just how small 0.1 micron is, the average human eye can see dust particles that are around 25 microns in size.
What HEPA Filtration Means For Allergy Sufferers
Dyson claims that their HEPA filters can trap particles as small as 0.1 micron. But what does that mean? And how will it help allergy sufferers?
The experts agree that dust mites and other allergens are as small as 0.1 to 0.3 microns. Which means a HEPA filter will trap all of the fine particles which are known allergy triggers.
Particles such as;
- Mould Spores
- Pet Dander
- Dust Mites
Are all known to cause discomfort in allergy sufferers.
However, it’s not just those minute particles that allergy sufferers have to contend with. Apparently it’s mid range particles that are most likely to become lodged in the lungs.
Which can be caused by: tobacco smoke, metallic fumes and some bacteria.
So whether you have a serious condition like asthma, suffer from hay fever, or are living with other respiratory conditions or even cardiovascular disease, a HEPA filtration system will have beneficial health effects.
Should You Use A Fan If You Have Allergies?
Many experts advise against using a fan if you have any allergies. This is because the fan can stir up and spread many dust, pollen and other particles.
Once disturbed, these particles are likely to keep circulating through the air for some time.
Which is why bladeless fans with HEPA filters are a better option. None of us like feeling too hot and using a fan is a great way to cool down.
For allergy sufferers using a fan can cause discomfort and in some cases fatalities. This is due to those minute particles. HEPA filters do a far better job of removing those minute particles.
If you want to cool down using a fan, you’re far better off using a bladeless air purifier fan.
Are Bladeless Fans With Air Purifiers Worth The Money?
Due to their air multiplier technology bladeless fans multiply their initial air intake by around 15 times. Dyson says their fans draw in about 20 litres (4 gallons) of air per second.
This means that their fans can pump out around 300 litres (65 gallons) from a 20 litre (4 gallon) intake. This is an incredibly efficient flow rate.
If you’re sold on the idea of a bladeless fan, you might as well go the whole hog and buy one with a HEPA filter. For the extra money, you’ll be buying better air quality.
And as we just saw, it’s not just those poor souls who suffer from asthma that will benefit from cleaner air. Cardiovascular disease includes heart disease, strokes and a whole lot more.
Plus there are several companies offering less expensive alternatives to the brand leader. Which means if you do your homework and price check all models, you could buy an air purifier bladeless fan with a HEPA filter for less than £150.
