How to Choose the Best Humidifier for Allergies
1. How big of a humidifier do you need?
Do you need a humidifier for the entire home? Answering this question may help eliminate some of the vast choices available for cool mist humidifiers. If you need a unit to cover a large room or an entire home, you can skip looking humidifiers that only offer coverage for small or medium-sized rooms.
You may want to look into a built-in humidifier if you own your home as this could help you reach the proper humidity level in the entire home year-round. They could help to reduce the frequency of maintenance and cleaning as well, but the initial cost of having this unit installed may put it out of budget for many.
2. Filter or no filter?
Some ultrasonic units have no filter or wick. This can sometimes lead to the humidifier propelling a fine white powder into the room, especially if you use tap water. Using a humidifier that has a filter may help reduce this as well as reduce the chances of mold or bacteria being spread through the vapor.
Some units offer a HEPA filter system that may help to purify the air as it humidifies, but these units can have a substantial initial cost and also may cost more to maintain due to the cost of HEPA filters.
If your humidifier has a filter, you may find that changing the filter helps to keep the humidifier clean and reduces the growth of molds. This can help to reduce the overall time spent cleaning thu humidifier.
3. Is this thing going to take all day to clean?
The easier the humidifier is to clean, the more often you will clean it. That’s common sense.
Cleaning the humidifier regularly is especially important for allergy suffers, and you need an easy to clean unit to ensure that this doesn’t become more of a chore than it’s worth.
Take a moment to look at the cracks and crevices you will need to keep clean, and does the manufacturer supply the propper sized brush to help get into these areas? If they supply you with a special sized brush you may want to look twice at the humidifier as it may be more difficult to clean than other models.
4. Are there humidifiers that are bacteria resistant?
Look for humidifiers that have anti-bacterial coatings so that the chance of spreading germs into the air is minimized. The last thing you need to do if you suffer from allergies is propelling mold or bacteria into the air.
Some humidifiers that offer UV bacteria protection while others have a coating integrated into the materials and both of these preventative measures may help reduce the possibility of spreading germs.
You may spend more time cleaning and maintaining humidifiers that don’t offer this protective barrier to germs, so you may not want to purchase the cheapest unit available because cleaning may be much harder than you expect.
5. What’s this white dust some humidifiers make?
While most humidifiers are listed as tap water-friendly, the lack of a filter in an ultrasonic humidifier may cause the unit to propel this fine dust into your home. The dust is a residue from minerals in hard water and can lead to a buildup on humidifiers internal parts, and this can lead to a host of problems.
It seems that evaporative humidifiers don’t suffer from as many problems from the use of tap water, so keep that in mind when you are considering a unit for your home. If you suffer from breathing allergies, the last thing you want from your humidifier is for it to produce this fine white dust.
6. Are there special humidity levels for people with allegies?
Speak with your doctor about the proper level of humidity you should have in your home. They have an understanding of your allergy issues and should have helpful suggestions about a good humidity level.
On average, the best humidity level for maintaining optimal health is between 35-50%, but if you have some allergies, your doctor may see fit to adjust this percentage. Having too much moisture in the air in your home may not only cause additional breathing problems but could also cause condensation buildup and the growth of molds and mildew.
You may want to look closely at humidifiers that have multiple vapor settings so you can adjust the output level as necessary without having to purchase a new unit.
7. Can you use the humidifier if you travel or change rooms?
Some units will allow for this as they offer different vapor levels, and this may make them suitable to use in different sized rooms. However, all humidifiers come with a recommendation for the room size that is best suited to the humidifier’s abilities.
One bonus of the evaporative type of humidifier is that it cannot over humidify the air, but you still must purchase a unit that is the proper size for the intended room. If you purchase a humidifier that is too small for the intended room, then you may not notice any improvements in your allergy issues.
