Waging War on Pollen, Dust, Bacteria, Mold, Germs & More with the Honeywell Air Purifier HHT-145


Sneezing, coughing and runny noses as night. Itchy eyes with tears being squeezed out. My daughters have had allergies all spring and summer and it was particularly worse this year because of the longer rainy season and the larger amounts of pollen in the air. So I brought some big air defense weaponry in to battle these tiny, annoying irritants, the Honeywell Air Purifier HHT-145.


This Purifier packs some major defenses against all of those items that can irritate the sinuses. There are 3 levels of protections in the Honeywell purifier:

  1. Ultraviolet Power – this is the best way to take out viruses, bacteria, fungi, mold spores and germs.
  2. HEPA filters – using a HEPA filter, you can effectively remove up to 99% of airborne particles including dust, pet dander, smoke and pollen.
  3. Odor filters – as the filters work, odor particles are removed as well, controlling pet, cooking and other smells.

Homes are places that are pretty laden with allergens and irritants and other pollutants, believe it or not, even more than you experience outside. Just think about all of the dust that you see coating things around the house. And one big thing that is full of dust (and even dust mites) are stuffed animals. We have enough stuffed animals in our house to open our own store and all too frequently they get shoved under the bed or in a corner somewhere just to collect more dust.


A lot of times, companies claim that their products are amazing and truly work, that is what marketing is all about. So, without having a ton of scientific measuring devices nor a clean room for testing in a controlled environment, I needed to figure out a way to test the Honeywell HHT-145. I used my children as test subjects. Their room proved to be the perfect environment: it could be closed off, it had lots of activity and consequently dust, there are plenty of stuffed animals under the bed, and both of my daughters whose room it is had been having bouts of sneezing attacks over the past couple of weeks.

While not scientific, this test case was definitely very “real world.” Turning the HHT-145 on solely consisted of pushing the power button. It turns on with all of the various filters and fans going, but in a low state. If you want to quickly clean a room, you should close the windows and doors and crank up the fan to a high setting. When I did this, you could smell the ionization happening as it was sort of an electronic smell. This is normal for air ionizers.


The ionizer injects negative ions into the air. In this case, negative is a good thing. You find negative ions in places where water crashes into rocks like waterfalls, beaches and streams. Positive ions, the bad type of ions, are found with pollution. One of the Honeywell’s defense against “all things bad” floating in the air, is the ionization filter.

You can turn the ionization filter on and off, just like you can control the speed of the fan; the higher the fan speed, the faster you can clean a room. There is also a button to turn on and off the oscillation of the filter. When the fan is high, and you have the oscillation on, you can actually get quite a bit of air circulation going on in a room.


The top LCD display also has a variety of other controls and readouts, including:

  • Cleaning Power button – turns on the fan that sucks in the polluted air and sends out purified air. There are 12 levels of cleaning power.
  • Timer button – lets you set the duration for the cleaning and then shuts down the purifier when the time has lapsed. You can set it to 1-18 hours duration.
  • U/V button – lets you turn on or off the UltraViolet filter
  • Ionizer button – lets you turn on or of the ionization filtering
  • Oscillation button – turns on and off the rotation of the purifier itself
  • Filter cleanliness meter – lets you know when you need to clean your filters

My kids turn the device itself off in the morning by simply pressing the power button. It’s that simple. The HHT-145 can clean a room up to the dimensions of 12’x15′ or approximately 185 square feet. You can do larger rooms but the effectiveness might not be the same. Ideally, you want to work in an room that is completely enclosed to ensure that all of the air therein is circulated through. This obviously depends on the size of the room and how long you have the purifier on as well as what level you set the fans on.


The cleaning steps used by the purifier are:

  1. Fan – fan quietly pulls in air through filters
  2. Air passes through a carbon zeolite filter (reduces odors & gets larger particles)
  3. Air passes through UV light to reduce and event eliminate airborne bacteria, viruses, mold spores and fungi
  4. Another permanent filter captures most of the airborne particles that are 2 microns or larger
  5. Air passes through an ionizer to clean the air and boost negative ions

After running the Honeywell for a day or two, I asked my children if they were sneezing more or less or having any other issues. They positively stated that they actually feel that their noses are more clear and they are breathing better. Obviously, this is not scientific proof, but the mere fact that they do feel that things have gotten better is very encouraging.

To clean the permanent HEPA filter, you do not need to replace it, thus the wording “permanent.” When the filter indicator shows that it is dirty, simply remove the filters and vacuum them out to clean them. That is quite cost effective compared to other filters where you have to replace the filters on a regular basis.

HighTechDad Rating

The Honeywell HHT-145 air purifier is a worthwhile investment, especially since there are no filters that need to be replaced further down the road. It is extremely easy to use and set up and can be used to clean a wide variety of rooms in your house depending on the size of the room and how long you use the purifier. My children are now sleeping better, with less sneezing and coughing, which is a great thing as a full night’s sleep is critical to young bodies. The price point is reasonable, especially since you don’t have to keep purchasing filters. The purifier itself is very safe and the fan is tucked away from little fingers. It will also shut off if it is tipped over. I wouldn’t have it un-supervised in a room with toddlers, but if your kids are over 7 and know not to mess with things, it should be pretty safe. If it it out of the reach of little hands, you should be ok having it in toddler or baby rooms but be sure to read the instructions.

EASY TO GEEK FACTOR – is the device easy to get up and running
FAMILY FRIENDLY – does the device fit well into family environments
RECOMMENDABILITY– would I recommend it to others (more means “yes”)
PRICE POINT – does the price reflect the product function
OVERALL – my general rating

HTD says: The Honeywell HHT-145 purifier is a critical household item which is almost as important as having a good vacuum cleaner in my opinion. With it, you can wage war on those tiny particles that cause allergies and pollute the home environment.
