Holmes HAP9422-NUA Price
First of all, the Holmes HAP9422-NUA is not even the latest product of this brand, the Holmes HAP9424B-NU is the upgraded version of our today unit. The Holmes Group wants to bring to you a device that doesn’t cost you the earth, but having a solid build enough and stylish appearance to look at. It is undoubtedly stylish and quite cheap, with support of a HEPA-type air filter and an ionizer to deal with the impurities. However, we are not in the past, and there is a lot of air purifiers with real True HEPA filter to keep your indoor air quality better in this price range.
So, Holmes HAP9422-NUA doesn’t have the unique selling point anymore. The GermGuardian AC4825 and GermGuardian AC5000 can do a lot better than this device, and you can easily tell from near 10000 reviews of them on Amazon. There is no way you could select this Holmes HAP9422-NUA, or even the new Holmes HAP9424B-NU at the moment.
For the price, the Holmes HAP9422-NUA is only $79, which seems like a big no-no to buy it right now. Perhaps the Holmes HAP424-NU or Holmes HAP242-NUC are the easier options to pick, with $10 to $40 less than our today Holmes HAP9422-NUA.
If you can stand sacrificing the fan power, you will have more True HEPA options, like Levoit Vista 200, AeraMax 100 or Whirlpool WPT60 for around $80 – $100. They are all built like a tower air purifier, with modern appearance and better features to use.

Holmes HAP9422-NUA Design and Size
What will we have here? A tower air purifier with a solid leg build, making in bullet-shape like the old classic tower folks like PureGuardian AP2200CA or PureGuardian AP2800CA, but the Holmes HAP9422-NUA has two concave holes on top.
The size of this device is similar to the big tower air purifiers of GermGuardian, with 28 inches in height. It has a black-and-white paint for the cover, and the perforated holes are tidily arranged to deliver a classic back-to-front air flow system concept.
You will have a knob to edit the fan speed of this Holmes HAP9422-NUA. It can be found from the front of this air purifier.
Finally, the Holmes HAP9422-NUA weighs only 10.5 lbs, and thanks to the convenient handle, you can move it around your home easily.

Holmes HAP9422-NUA Filters
To decide the performance of one air purifier, you will need to know about the quantity and quality of its air filters, as well as the air filter types are used. The Holmes HAP9422-NUA has the 2-stage air cleaning system as below.
- HEPA-type filter – It is not a True HEPA filter, and the quality is much inferior. But the air filter from Holmes HAP9422-NUA is said to clean 99% of any particles down to 2 microns in size.
- Ionizer – The technology of ionizing air purification from Holmes, which complies the standard safety of CARB completely.
As you can see from the chart below, the actual performance of this Holmes HAP9422-NUA is still far from the threshold of 99% efficiency like advertisement. Notice that the HEPA-type air filter is inferior, which is not tested or certified anywhere to meet the standard of a HEPA. It is not just in the case of our today unit, it happened in the Holmes HAP9240-NWU and Holmes HAP242-NUC, too.
The HEPA-type filter of this air purifier needs to be replaced after 6 months, with a cost from $12 – $17. At the moment, you can buy the True HEPA filter for the Holmes HAP9422-NUA, with the cost of $44. However, at the time of writing, there is a great sales for the Holmes True HEPA air filter, and you can grab it below. With the True HEPA filter, the efficiency of Holmes HAP9422-NUA increased from 88% to exactly 99%, which is 10% in difference.

Holmes HAP9422-NUA Sound
The Holmes HAP9422-NUA has the noise level of about 55 decibels (db) at the highest setting. You can even hear the crackling noise from the ions inside this device, and some people even complained that even with the 3 fan speeds, the noise level didn’t reduce on lowest speed. My testing unit didn’t have this problem, but I guess I need time to check my device and will update the content as soon as possible.
But, just like other Holmes air purifiers, the Holmes HAP9422-NUA is clearly not good enough to use in the quiet places.

One of our most FAQs is “Do air purifiers use a lot of energy?” In fact, air purifier must be used for a long time to be efficient. And power consumption is one important criteria to review how much energy this air purifier will consume.

For running the Holmes HAP9422-NUA 8 hours per day, you need to pay $35 each year.

Holmes HAP9422-NUA Additional Features
Yet another Holmes air purifier without any additional features. The only things you can have from this Holmes HAP9422-NUA are one function to turn off the ionizer (to prevent the asthma trigger because of the high ozone emission from ionizer) and one indicator for filter replacement. Other than that, there is not much to explore in this air purifier.
Holmes HAP9422-NUA Customer Service
Even being acquired for more than 10 years, the Holmes products are still one of the most popular electric appliances today. Then the reason can only be their impressive customer service. If you need to contact them, you can easily do so by filling in the information at their Contact page, or calling them via phone at 800-546-5637.
Once you make an order, you will get your Holmes air purifier with a promotion of Free Shipping over $50. However, the promotion is only applied at the time of writing, so if you can’t find the Free Shipping option, you should choose to buy from Amazon. The most wonderful thing is, after your purchase, or any reason you are not completely satisfied with the Holmes air purifier, you can return your item within 30 days of receipt for an exchange or refund of the purchase price. Great, isn’t it?
And don’t worry about your air purifier, it will be backed up by a great 5-year warranty from The Holmes Group. This is also the best warranty for an air purifier brand that only targets low-range segment.
We don’t need to use the Holmes HAP9422-NUA, as the GermGuardian AC4825 can offer a much better performance. It is new era, and we wish that The Holmes Group should put their effort into making modern air purifiers, rather than staying in the shadow of the past.
No wonder why the Holmes HAP9422-NUA is discontinued anymore.
