Air Purifier for Bedroom?

Post by unstoppable » Fri Apr 19, 2019 7:22 am

Hi All,

I'm quite sensitive to smells, dust, and other allergens. I recently had some work done on my closet where they cut into the dry wall. I'm not sure if a lot of dirt/dust has moved around the house, but ever since every morning I wake up very congested. My eyes are extremely puffy, my nose is all clogged up, and typically my mouth is as dry as possible. It could be a coincedence, but it seemed to happen right after the work was done.

I'm going to replace my AC filter this week as I normally do (although sooner than usual), but was considering buying an air purifier for my bedroom. I've looked on Amazon and other sites, and there seems to be an unlimited world of different brands, types, filters, sizes, prices, etc. I've read a few articles, but figured you guys might have some first hand experience. I've heard before they don't do much, and I've also heard others swear by it in the past.

For example saw a deal for one/highly rated here:
https://kinjadeals.theinventory.com/bre ... searchpage

I've also been looking at the top rated/amazon choice on Amazon as well.

Does anyone have a lot of experience with these? Ideally I'd like one that is light weight, easy to setup, not a lot of maintenance, and actually makes a significant difference. Is there a certain place to put it? On my floor? next to bed? Do I keep it on all day/night?

Thanks in advance! *sneezes*

You probably want something with a HEPA filter. HEPA just means it filters out 99.97% of particles 0.3 microns or larger.

I have a Honeywell HPA300. It also has a thin sheet of activated charcoal which is like a pre-filter. It works pretty well. You have to vacuum the dust from the pre-filter periodically. The actual HEPA filters are also replaceable. There are other models, this one takes 3 of the standard replacement HEPA filters, I have a smaller model that takes 2.

I'm not sure how it compares with the Conway.
Just because you're paranoid doesn't mean they're NOT out to get you.

Pollen has been particularly bad in our area, maybe yours as well? If you take a pill, do your symptoms go away?

We use BoAir permanent air filters that one washes periodically. They do a great job of trapping dust and other stuff. I just used my power washing to clean them, but below is a photo AFTER running the rug vacuum cleaner over a portion which is still somewhat dirty (the squares are about 3 to an inch or close to about actual size) and BEFORE power washing:

I have the Coway and my wife thinks it works well. We have it at the head of our bed, its very quiet. It has an auto feature that will wake you up in the middle of the night if it goes on high. It is less then 3 feet from our heads though. I would buy it again.

We have had one of the larger Winix units in the past. They go on sale at times for around $100 at Costco.

You can try a DIY approach for $20 if you have a box fan. See:

I have this in two of our bedrooms. I use bungee cords to secure the filter to the box fan..

Be sure that you’re not sensitive or allergic to something in your bedding.

This is a good place to research air purifiers.

When I researched them a while ago, this was my pick, although I never actually bought one.

Seriously, the DIY is worth considering. There's a guy who was testing these against commercial air purifiers w/ an air particle counter in Beijing and his data shows that this diy approach works really well. (It's kind of scary just how bad the air there is!!!)

We've used a Winix air purifier with a HEPA filter.

Some allergies are related to dust mites. To attenuate dust mites, put an allergy specific mattress cover over your mattress and wash your sheets once a week in hot water (130F+). Alternately, run them through a dryer at 130F+. We also use better quality air filters in our furnace/AC. If you want to get into the weeds on the topic, look up MERV and ANSI/ASHRAE Standard 52.2. If you decide to invest in a HEPA filter, check into the cost, availability and replacement schedule for the disposable portions of the filters.

One complaint I have regarding furnace filters in the big box stores is they typically give some non-standard manufacturer's rating for filter performance which doesn't conform to the industry standard MERV ratings.

In addition, put "allergy proof" cases on your pillow(s). The regular pillow case goes over these.

As close to your bed as you can reasonably get, and close the doors to your bedroom at night. If the problem is only dust and particles, a simple HEPA filter would do the job, and I would start there. The problem with any purifier is that it only cleans the air that moves through it, so to do a good job you have to move a lot of air and that means noise, although some designs are quieter than others. If the problem is odors and gases, the best solution is good ventilation, but that's not always practical, especially in winter, and it brings in pollen from outside.

I have one of these, and am currently using it to control paint fumes from the unit below mine. The good thing is that it actually works. Less good things are the price and the need to replace the filters regularly. But it really does work.

Looking at that website, those (expensive) "multi-gas cartridges" use activated carbon. Which makes perfect sense as activated carbon is known to be good at absorbing VOCs and odors.

Empirically speaking, I've actually been running my diy box fan filter w/ an activated carbon pre-filter. Primarily, it's to save and extend the life on my expensive ($10) 3M filtrete filter, but I've found it to be very effective at removing strong cooking smells like bacon. It's $8 for a 16" x 3 foot cut-to-fit roll of activated carbon: https://smile.amazon.com/Cut---Fit-Carb ... bon+filter


This guy tested activated carbon against formaldehyde and VOCs from cigarettes:

As a long-standing victim of allergens, note much of the above is very good advice.

Would just add that providing all other obvious measures taken to combat allergens, then an Air Steriliser is the quietest piece of equipment for a bedroom (with no moving parts), and reasonably efficient at destroying all airborne particles, odours, etc.
However relying on convection, Air Sterilisers take a day or so to clear a room, so be prepared not to open doors and windows too frequently.
For rooms other than a bedroom where noise is not an issue we do use a Winix Air Filter as recommended by others above.

I have one in my bedroom - works well, is quiet, but has to be reprogrammed if unplugged. In my experience the filters last a very long time, although I have it programmed only to operate at night, which is likely extending the life of the filters.

Just like always, it takes me forever to "pull the trigger" and buy something, paralysis in the analysis...which is even easier to do in the massive amount of products online. When I was younger, I'd just buy whatever was in the store, in the price range I wanted.

I've been looking at this one recently:
https://www.amazon.com/Airthereal-APH26 ... ay&sr=8-17

Does anyone have the above one? I will be ordering one this week, as I'm still waking up very congested, and I have a scratchy throat.

Austin Air is the brand that I use.

Expensive initially, but filters last 5 years.

Been on constantly for 10 years.

Noisy, so if you are sensitive to white noise may not be for you.

I use a DIY. Noisier but it's just white noise and it can be placed farther away because it can circulate more air than those silent ones. But the real reason I use a DIY is because I want to be able to use it on the window to get some fresh air without the pollen.
