What’s more, they can also grab a hold of particles as small as 0.3 microns in size! Try to beat that with a regular, old-fashioned filter!
Another plus point in most GermGuardian filters is their UV-C light, which has antimicrobial properties. The UV light has been present in most modern air purifiers but GermGuardian’s technology is one of the earliest around, so it’s most likely more developed than the rest.
Their charcoal filter is also part of their 3-in-1 system. What you may like about this is that it can absorb bad odors, such as the smell of your dog, the smell of your smoked fish, and the like.
Most GermGuardian air purifiers also have the following:
- Fan speed control. This would be useful so that your motor life would last much longer. It would also be great if the fan speed can be adjusted according to how severely polluted your indoor air quality is.
- Energy Star certification. This feature is important since anything that is Energy Star certified can help the environment a lot (and likely reduce your electric bill as well).
- Limited lifetime warranty (3 to 5 years). Having a limited lifetime warranty can really give you peace of mind since the company is in good faith with you.
How do I choose the best air purifier for asthma and allergies?
In order to look for the best air purifier for allergies and asthma, you should spot the following:
- Low noise level. Having a low noise air purifier can help you get some shuteye. If you are a light sleeper then you’d best bet on a low noise unit so that you won’t get distracted. After all, some people can’t sleep with a running motor noise in their room.
- True HEPA filter. Compared to a regular HEPA filter, the True HEPA filter can clean up to 99.97% of airborne particles, dust, allergens, pollen, and the like.
It is more powerful than your average air filter so it may have a better chance of clearing up your surroundings against particles that may trigger your allergy or asthma.
- Activated carbon filter. Sometimes, smoke from fish and other sources could cause you to sneeze or have difficulty in breathing. An activated carbon filter does the job by eliminating or at least minimizing the number of smelly particles in the air.
- Higher CFM or fan speeds. Having a faster CFM and fan speed can help to eliminate more allergens in the air, which can be ideal for those with asthma or allergies.
This would also be helpful if it’s hay fever season, where pollen counts could be massive in your area. Higher fan speed can move air much faster and thereby possibly helping you breathe better.
- Eco-friendly modes. An eco-friendly mode is described as something that can minimize the energy consumption of your air purifier. For instance, it can automatically shut off when no air pollution has been detected. For this to work, your air purifier needs to have an automatic sensor that detects the level of pollution indoors or wherever the unit has been placed.

Do air filters really help allergies?

- A filter layer for larger particles
- A layer that is made for smaller particles that are micron-sized
- A carbon layer that can remove odor and the like
- A layer that may disinfect your indoor air with UV-C light
- They can also remove VOCs. Volatile Organic Compounds are particles that come from chemicals that are harmful, such as sprays and household cleaners. To remove them, you would need a quality air filter.
- Most of them have a carbon filter. The carbon filter can possibly help to remove odor from your indoor air, such as those coming from smoke, chemicals, and the like. Carbon filters are usually tied to the true HEPA filter system.
Air filters and purifiers can work against allergies provided that they are:
