Only the best items make any of our lists to enhance your shopping experience.

Cleans the room air at 97% accuracy or above

Each one of these air purifiers will clean the room air of at least 97% of all bacteria and pollutants. Because of the HEPA filters, this is possible with all of the featured products. You can be sure that most air contaminants are being captured in the filters of these units because of the high success rate of these purifiers. They all clean the room air at least three times an hour to give you the purest air to breathe in your home.

Easy to operate, setup, and understand

Air purifiers are simple to operate and set up. The hardest thing is deciding which room to put them in and where to place them in the room. The room that has the most traffic will be the best room in the house to put the purifier, or if it was purchased for a certain person in the house because of breathing issues, then it should go in the room they are in most of the time. Setting up an air purifier is best done by following the instructions carefully. Just be sure to take note of any issues that can occur in operating the unit.

Have HEPA filters for best performance

Air purifiers with HEPA filter systems are the best units because these filters catch the most harmful particles in the air. Microscopic bacteria, mold, mildew, smoke, and pet dander, for example, are trapped in this filter much better than other filters. Most of the air purifiers we feature have these filters, making them the best products offered online. Most of these units have 97% or above capacity to trap these substances in room air to prevent you and your family from breathing them in.

The Importance of Air Quality for Children’s Health

Because kids breathing functions are different from adults, they take in more air when they breathe than grown-ups. As most of us spend the majority of our time indoors, the air in our homes and offices matter significantly. Studies have shown that indoor air can be polluted more than 100 times than outdoor air. Some common signs of exposure to pollutants in the air are scratchy throat, itchy nose, nausea, dizziness, tiredness, and headaches. Breathing disorders, cancer, and asthma are serious effects from breathing unclean air.

Asthma affects over six million children in the U.S. alone and is a severe issue. Asthma causes other medical problems along with difficulty in breathing and participating in activities. Other medical problems that can result from asthma are anxiety, sleep apnea, and gastroesophageal reflux disease. Because there is no cure for asthma, parents can only care for the symptoms of the condition and eliminate the triggers that set off attacks. One great tool in helping asthma sufferers is a great air purifier.

Common triggers for asthmatic children are mold, pest droppings, secondhand smoke, dust mites and dust, mildew, outdoor allergens such as pollution and pollen, and volatile organic compounds such as cleaning materials, paints, or plastics. Asthma in infants can be linked to secondhand smoke, the presence of cockroaches or dust mites in the home, a mom with asthma, being born too early, and viral infections. Reactions to asthma for the child depends greatly on the exposure the mother has to pollutants when pregnant and the age of the child. Individual filtration units in separate rooms of the house work more effectively than a system that treats the air in the whole house. It is essential that air purifiers be turned off right after vacuuming in a room to catch all of the agitated particles in the air.

FAQ

Frequently Asked Questions

Q: Are these air purifiers easy to install, understand, and use?

A: Each one of these comes with instructions for setup and operation to make using an air purifier simple and trouble-free. They all come with starter filters to help with the ease of operation, so all you need to do is remove all wrapping, plug it in, and choose your settings. It is best to familiarize yourself with the instructions fully before operating and setting up the unit.

Q: Which ones are best for large rooms? Best for small rooms?

A: For large rooms, the larger, more expensive units would be best, such as the Rabbit Air, Levoit LV-PUR131, and the Coway model. These can all handle the capacity of a large room well. For small rooms choose the Hamilton Beach product, the Germ Guardian item, and the Levoit LV-H132 purifier.

Q: Which ones are the least in noise?

A: Although some claim to be less noisy than others, each one of these does make some noise. For light sleepers, we would suggest keeping the purifier on a low setting and place it as far from the sleeping area in the room as possible. If there is a night light on the product, then face it away from the bed, so the light will not bother the sleeping person. None of these are truly noiseless in their operation because they do contain a motor.

Q: Are any of these portable that can be moved from room to room easily?

A: Yes, the product from hOmeLabs is a portable unit, but other smaller purifiers can also be moved from room to room because of their compact size. These would include the Hamilton Beach model, the Germ Guardian product, and the Levoit LV-H132 item. They are all small and easily transported.

Q: Does a person have to sit near one of these purifiers to receive the cleanest air in the room?

A: No, you do not have to sit near these systems to receive the cleanest air in the room. The air in a room is filtered many times an hour, so operating at a normal speed, all of the air in a room should be the same level of clean.

Q: When during the day and night does one of these need to be operating? Do they run all day and night?

A: The times of operation depend on the conditions of the room and the people that are in it. If you have a child with asthma or other breathing condition, then the purifier should at least run on low for the whole time the child is in the room. For just regular use in a room where no one is staying, the unit can be operated only in times when the room is occupied. If there is a pet in the room or in the house, it would be advantageous to have this filtering system on to pick up any floating pet dander and dust in the air.
