It’s not the cheapest smart air purifier by any means, but if you love the excellent performance from Honeywell products, it may be perfect for you. Okay, let’s get back to our Honeywell HPA8350B Review.

Other Honeywell’s Air Purifier Reviews

Honeywell HPA8350B Price

Honeywell has always really excelled at making mid-range air purifiers, in the way competitors like GermGuardian and Envion don’t have, the high-quality True HEPA filter combining with high fan power. Such high performance is enough to market the Honeywell products, even though they don’t have any good smart features like Coway and Winix did with their air purifiers.

However, the company is trying to change that with the new Honeywell HPA250B and today, Honeywell HPA8350B. If you regularly need to change the settings of your air purifier, Honeywell thinks this is the device for you. While the flagship Honeywell HPA600B may have the best True HEPA filter ever, with the same performance as old Honeywell HPA300 and great Smart features, this air purifier will be your favorite one soon.

This is unmistakably a mid-range air purifier though, and you can buy the Honeywell HPA8350B with only $299 in the official Honeywell store. The price may varies from different retailer, and I’m happy to give you a deal of this air purifier below.

If your budget can stretch a bit further, you can look for the competitors of this air purifier like Dyson Pure Cool Link, which also packs with great smart features. The Winix AM90 and Blueair Classic 205 are also some prominent alternatives, especially when they can be connected with Alexa.

Honeywell HPA8350B Design and Size

Constant, rapid progression: it’s seen as the natural state for not only air purifiers, but any other devices. The Honeywell HPA8350B looks exactly like the Honeywell HPA300 from the outside and inside, which doesn’t buck the trend Honeywell did with previous Honeywell HPA250B.

It only comes with the signature Honeywell color option, the Black version. You won’t be able to get the default White from Honeywell this time.

Honeywell has always made air purifiers that revel in a certain angular sturdiness, and the Honeywell HPA8350B doesn’t buck that trend. Keeping the same size of 22 inches in height and 21 inches in width, the device ensures that it’s firm enough to stand on the ground.

Like the whole Honeywell family, the Honeywell HPA8350B makes use of the bottom-to-top air flow system concept, which is also the most proper air flow direction for console air purifiers.

The Honeywell HPA8350B has a similar top control panel like the HPA250B, with new Bluetooth function.

It’s also relatively heavy like the HPA300, with 24 lbs in weight. However, you can easily move the Honeywell HPA8350B around your home, thanks to two convenient handles.

Honeywell HPA8350B Filters

Like the non-smart Honeywell HPA300, Honeywell HPA8350B runs the exactly powerful air filtration system, with core as the True HEPA filter.

  1. Pre-filter – The pre-filter has Activated Carbon filter in it. This will both help adsorb VOCs, gases, odors and trap larger particles. However, as a combination with a carbon filter, this pre-filter needs to be replaced after 3 months.
  2. True HEPA filter – The heart of this air purifier is a True HEPA filter to capture up to 99.97% of as small as 0.3 microns pollutant particles like pet dander, mold, viruses, bacteria and pollen.

We don’t need to discuss more about the high quality of air air filters from Honeywell brand, it is just superior for the price. The performance is too good to be applied in any models of Honeywell family, even since the first HPA100.

It’s satisfactory, but you may need another test for the performance of this Honeywell HPA8350B, right? In a room of 200 square feet, I let the device run in 1 hour, and it reached high efficiency of 99.95% without any problem.

The Honeywell HPA8350B sports the same HRF-R3 air filter like the previous HPA300. You will have a pack of three air filter, costing you $68, and each air filter can easily last for one year.

Honeywell HPA8350B Room Coverage

Honeywell HPA8350B, apart from its obvious smart features, is exactly the popular Honeywell HPA300 at its core. Well, it can easily cover a room of 465 square feet, thanks to its high fan power.

The ACH of Honeywell HPA8350B is 5x. The air changes per hour rating of this air purifier is really impressive, and it can exchange the air every 12 minutes.

The CADR of Honeywell HPA8350B is 320 Dust/ 300 Smoke/ 300 Pollen (cfm). This fan power is only below the trio of Dyson Pure Cool Link, Dyson Pure Hot+Cool and Dyson Pure Cool Tower, because the Dyson air purifiers are designed to be the cooling fan as well, so it needs much more fan power to deliver the air flow continuously.

Honeywell HPA8350B Sound

Again, nothing is fixed from the previous models, and the Honeywell HPA8350B is another device with high, but noisy fan power. Well, it is the nature of most common air purifier, so you should expect this weakness.

If you are planning to purchase one air purifier in your office or when you sleep, you should think again about Honeywell HPA8350B. Actually, the new device has an Auto Mode, to keep it mostly on lowest fan speed, thus reducing the noise level to as low as possible.

Honeywell HPA8350B Power Consumption

One of our most FAQs is “Do air purifiers use a lot of energy?” In fact, we need to run an air purifier for a long time to be efficient. And power consumption is one important criteria to review if this air purifier is a must buy or not.

The Honeywell HPA8350B keeps the same rated power as the HPA300, which is 40 watts at the lowest setting. If you run the device on Turbo fan speed, the power consumption can be as high as 130 watts. Yes, 130 watts are pretty high for a common household air purifier. It is still an air purifier with Energy Star rating, thanks to efficient CADR/watt rate.

If you run the Honeywell HPA8350B for 8 hour per day, you need to pay from $15 to $47 each year, depending on the most used setting.

Honeywell HPA8350B Additional Features

This is where the Honeywell HPA8350B differs from the previous models of Honeywell family. The additional features are also the reason you buy this air purifier instead of the famous Honeywell HPA300. Of course, the price tag is higher, but it gives you the most complete Honeywell mid-range air purifier.

So to say, we will have the Smart control, via Bluetooth v4.0 in any Apple or Android devices. You can operate your air purifier from another room in your home within 30 feet of the Bluetooth Smart device. Within the app, you will have many new features, like an Auto Mode to automatically operate for allergens and VOCs, a proximity sensor to detect when you are in or out the Bluetooth range, and turn off the air purifier.

The Honeywell HPA8350B also has a Timer to schedule time off for your device, with 3 different values of 2 hours, 4 hours and 8 hours. There are also 3 fan modes besides the Turbo: Allergen, General clean and Germ.

We also have a dimmer setting, to reduce or turn off the light on top control panel. Finally, you have a LED indicator for filter replacement.

If you are looking for a Smart flagship air purifier of Honeywell, you can look for Honeywell HPA600B.

Honeywell HPA8350B Customer Service

Honeywell is a leading brand in air purifier market, but they don’t offer a friendly customer service as others. You can reach them via mailbox of Honeywell Store in 407 N. Quentin Road, Palatine, Illinois. But I suggest you should call them at 847-701-3038 for any support questions. Or you can email to for any problems you experience while on the site or after buying a product. Honeywell is available from Monday to Friday.

They don’t have Free Shipping like Rabbit Air or Alen, and you must notify them within one business day for any problems with third-party shipping service like USPS or FedEx. Otherwise, they won’t take responsibility for any merchandise damage in transit. Also, the shipment can take up to 10 business days from the date that the order is shipped.

The hardest part is when you want to return one Honeywell air purifier, as you only have 30 days from the date you receive your item to process your return. You won’t receive the shipping charge (on both the original shipping charge and the return shipping charge) and must pay a 10-30% re-stocking fee if there is no damage caused by transit or workmanship defects.

The warranty policy of Honeywell is also among the longest to guarantee against all defects, with up to 5 years warranty.

Our verdict

The Honeywell HPA8350B makes the Honeywell HPA300 a complete air purifier, with high-end smart features. It grants all the benefits for having the most popular Honeywell air purifier, but it also keeps all the previous problems, too. The price is also a bit higher, so unless you love the smart features, I advise to stick with the HPA300 instead.
