Holmes HAP412BNS-NU Air Purifier: Trusted Review & Specs

After the Holmes HAP9424B-NU, this company discontinues the next duo of Holmes HAP412BNS-NU and Holmes HAP412N-U, which we are too lucky to have these two testing units, and I, Brook, have chance to write the Holmes HAP412BNS-NU Review for my beloved readers. It is also true for the different color option – Holmes HAP412BNS, too.

The air purifier seems to be discontinued, so we recommend you to check the review of Holmes HAP8650B instead. Or if you need a desktop air purifier, you can search for the Holmes Desktop Air Purifier.

Holmes HAP412BNS-NU ranks D+ in our air purifier ranking list. We give the biggest and most thorough database of air purifier reviews in the world.

UPDATE: As the Holmes HAP412BNS-NU appears to be fully sold out, I recommend properly checking our deal before reading this review, as the review itself is pretty lengthy.

In Breathe Quality, we have reviewed all air purifiers under these sections. Also, we guarantee that:

  • We do give honest reviews (both pros and cons) so anyone will guarantee to have the wisest choices.
  • We do not (and never) exaggerate one product just to let you click the links and buy that product blindly.

Holmes HAP412BNS-NU Price

Air purifiers by their very nature are capable of purifying the indoor air, and all to often you don’t really care much about the actual air purification technology. You just want to know if it works, and the air purifiers with HEPA-type filter like Holmes HAP412BNS-NU and Holmes HAP242-NUC are the cheapest device you can get for a proper performance.

Many other air purifiers can give you the real True HEPA filter for such less money now, like the Levoit LV-H126 or PureZone Halo. The options are unlimited, but this is not the situation in a few years ago, when with so less money in your pocket, you can only choose the inferior air purifiers.

To be fair, the Holmes HAP412BNS-NU and Holmes HAP412N-U prices are crazily low, as both these air purifiers are only $49. To have the True HEPA filter, you should choose the Holmes HAP706-NU instead. If you are in Canada, you can also select the Bionaire BAP1412-U instead, to have the espresso color option, as well as the stylish perforated air vents.

Holmes HAP412BNS-NU Design and Size

Before the appearance of Holmes HAP9422-NUA and Holmes HAP9424B-NU, the Holmes HAP412BNS-NU is the tower air purifier type of this company. However, it is only 16 inches in height, which is just taller than a typical compact tower device like Levoit Vista 200.

There is no bullet-shape design like the bigger brother, Holmes HAP412BNS-NU only comes with a solid build of the classic neat all-in-one kit, and somehow I have felt a strong resemblance as the device of Honeywell – the Honeywell HPA060. Yes, it is definitely the same big air grill on front, but the Holmes HAP412BNS-NU will use the old back-to-front air flow system concept, while the representative from Honeywell will choose the better bottom-to-top concept.

I have found one minus from this air purifier, the air filters do not totally fill the space inside, and there is a chance that polluted air can escape the air filtration system. This is a normal defect from the cheap air purifiers, and Holmes HAP412BNS-NU is not an exception.

On top of this device, there is two switches to change the fan speeds and turn on/off the ionizer function.

Holmes HAP412N-U weighs only 7 lbs, and this is a very small air purifier to pick up.

Holmes HAP412BNS-NU 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 HAP412BNS-NU has the 2-stage air cleaning system as below.

  1. HEPA-type filter – It is not a True HEPA filter, and the quality is much inferior. But the air filter from Holmes HAP412BNS-NU is said to clean 99% of any particles down to 2 microns in size.
  2. Ionizer – The technology of ionizing air purification from Holmes, which complies the standard safety of CARB completely.

I made the same test for the Holmes HAP412BNS-NU like in the Holmes HAP242-NUC or Holmes HAP9424B-NU, in a room of 100 square feet, and the duration of 1 hour. The final result, our Holmes HAP412BNS-NU had better performance than the desktop air purifier, as it was 84% for trapping any particles down to 0.3 microns. You can look at the chart below to see the final result of our test.

Holmes HAP412BNS-NU review

The HEPA-type filter of this air purifier, named HAPF30AT needs to be replaced after 6 months, with a cost from $17. At the moment, you can buy the True HEPA filter for the Holmes HAP412BNS-NU (HAPF300APD), 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 HAP412BNS-NU increased from 90% to exactly 99%, which is nearly 10% in difference.

The ACH of Holmes HAP412BNS-NU is 4X. This air purifier can clean your room in every 15 minutes.

Holmes HAP412BNS-NU Sound

As the compact version of the Holmes HAP9422-NUA, the Holmes HAP412BNS-NU is promised to operate quietly, and it seems finally we have one silent Holmes air purifier. The sound on lowest speed is fairly low, as it is about only 40 decibels (db). It is probably white noise, though I can’t check exactly the frequency of the sound.

But again, the problem with the noise is still available in this Holmes HAP412BNS-NU. If you want to sleep in silent, you should turn the fan speed to low setting.

Holmes HAP412BNS-NU Power Consumption

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.

The power consumption of this Holmes HAP412BNS-NU is only 45 watts, and it is a lot energy-saver than the taller tower air purifiers in this family.

For running the Holmes HAP412BNS-NU 8 hours per day, you only need to pay $17 each year.

Holmes HAP412BNS-NU Additional Features

Again, both the Holmes HAP412BNS-NU and Holmes HAP412N-U are the very old products of The Holmes Group, and as you can see from the simple control panel, there is only two manual switches to do the job. Other than that, you don’t have any additional features for these air purifiers.
