If you or any of your family members has asthma, allergy, or any kind of respiratory problem, you need to get an air purifier. And if you happen to have an extra-large space to cover, the Honeywell HPA300 True HEPA air purifier should be on your shortlist.
In this review, we’re going to talk about the design, build quality, performance, and price/value. At the end, we give our final verdict of whether this air purifier is worth your hard-earned money or not.
Since it’s made to cover living space as huge as 465 square feet, the Honeywell HPA300 is unavoidably big. It measures 9.2 x 20 x 22.2 inches and weighs 21 pounds, so it’s not something that you would want to move around often. You just put it on the floor near a power outlet, turn it on, and let it do its job.
The air intake is located on the front of the unit and clean air is blown from the top. The top portion also holds all the controls and lights like power, mode, dimmer, and check filter lights.
Design-wise, this air purifier won’t win any beauty contest anytime soon. However, the Honeywell HPA300 blends easily in any room so you can call that a plus if you will.
Honeywell has been in the business of air cleaning for 25 years and the HPA300 is clearly one of Honeywell’s many excellent air purifiers.
The build quality of this unit is good. It’s mostly plastic on the exterior. We have no problem with that because it’s not the cheap type of plastic. Early batches of this model have flimsy door latch issues, but no longer so for years now.
Honeywell gives you 5-year limited warranty. If you happen to get a defective product, you can return it to have it repaired or replaced.
Performance is where the HPA300 truly shows it means business. This unit is rated for living space up to 465 square feet and it does its job really well. It does it so well, in fact, that some customers trust it enough to clean up the air in a 1,500 square feet room.
The HPA300 does an incredible job cleaning the air in your home since it uses three HEPA filters that trap 99.97% of airborne pollutants as small as 0.3 microns. To put that into perspective, pollen is about 30 microns, household dust is 10 microns, pet dander is 5 microns, and smoke particle is about one micron in size.
This unit also does a great job at reducing foul odors in the house thanks to the carbon pre-filter. If you have pets in the house, this unit will prevent your whole house from smelling like them.
The HPA300 has three modes that tell you how fast it’s cleaning the air in the room. The modes are Germ, General Clean, Allergen, and Turbo.
Germ is the lowest setting and it’s the ideal mode when you use it in in the bedroom at night. This air purifier whirrs quietly just like a small fan running. Even light sleepers won’t be bothered by it.
“Hmm, I’m not sure the lowest setting will cut it.”
Don’t worry, you can set it all the way to General Clean if you want to. It sounds a bit louder than the Germ setting, but it does serve as a good white noise.
On turbo, the HPA300 is able to filter and circulate the air in the room five times an hour, or once every twelve minutes. This 5X number is referred as the ACH rating which is short for Air Changes per Hour.
This rating is a crucial factor to consider when buying an air purifier. An air purifier with 5X ACH rating is superior compared to air purifiers with ACH rating of 4X or less.
There’s another number (or more precisely a set of numbers) that defines the Honeywell HpA300’s performance; the CADR rating.
CADR stands for Clean Air Delivery Rate and it’s a set of three numbers denoting how well an air purifier can clean the air in a specific room size. The CADR rating for the HPA300 is 300/320/300. These numbers correspond to tobacco smoke, dust, and pollen.
Let’s talk about the CADR rating of 300 for tobacco smoke for a second. This number means the HPA300 can reduce smoke particles as if you’re adding 300 cubic feet of clean air each minute into a 465 square feet room. That makes it one of the best air purifier for smoke.
“How will this translate in real life?”
Ok, let say you have a guest coming over who casually pulls out and lights up his cigarette. Your passive aggressive remarks about his stunt just zoom past his head and he just keeps blowing foul smoke all over.
Instead of grabbing him by the collar and throw him out of the house, you can just turn the HPA300 on full blast. You get your fresh air back and the sound will drown any his worthless yapping.
Do note that the HPA300 is an AHAM certified air purifier, which means Honeywell didn’t pull the ACH and CADR rating out of thin air.
AHAM is short for Association of Home Appliance Manufacturers. This organization verifies the performance of various home appliances that people use daily.
“Why should I care?”
You see, AHAM did all the homework for you. They tested appliances in independent testing labs to check an appliance’s performance against its published specifications. Therefore, when you see an air purifier with AHAM verified badge on it, you can be sure the manufacturer isn’t making bogus claims about their product.
One thing that we must warn you is that this air cleaner cannot trap Volatile Organic Compounds (VOC). If this is a concern for you, we suggest planting common houseplants as described in this short TED talks video.
Before you buy an air purifier, you need to think about the extra cost it entails. The first is the cost of filter replacements.
The HPA300 uses one carbon pre-filter and three HEPA R filters that are not washable. Honeywell dictates that the pre-filter should be replaced every three months.
It needs frequent changing because its job is not only to reduce odors but also trap large airborne particles to ease the HEPA filter’s jobs. The HEPA R filters, on the other hand, only need replacement once a year.
Considering all the good stuff the Honeywell HPA300 comes with, it’s hard not give it our heartfelt recommendation. Sure, there are many less expensive choices available, but the Honeywell HPA300 air purifier provides an excellent performance at a decent price point. We definitely recommend you get this one if you need an air purifier for an extra-large room.
