Air Purifier Advice Needed

Recommended Posts

I need to get a hold of one of these but need some advice and recommendations. It’s for a 80sgm condo which is made up of living room leading onto dining area then kitchen. Toilet is obviously a seperate room as is the bedroom. So, do need to go for an 80sqm? I take it even when all the doors are closed inside if the purifier is just in one room it purifies all three rooms?

Next, recommendations on model, price and where to get,,, lazada, power buy etc.

cheers

It cleans the air in the room it is located and has airflow - not sure what you are asking but normal use would be use in living area during day and bedroom at night (unless you want to have two units).  Most bathrooms would not want as you need fresh airflow for smells (and often an open window).

 

So you need a unit that is rated for, or close to, the size of your LR or Bedroom (whichever is largest).  Most are able to buy good units in the 4-6k range - make very sure replacement HEPA filters are and will be available (many units sold here this could be an issue).

Your windows should be tight and look where and for what price you can get replacement filters.

I bought the Xiaomi Mi Air Purifier 3H recently on Lazada. It is the latest model from Xiaomi. I bought it after reading some good reviews.

 

It works well and has a PM 2.5 meter with display build-in. They are around 5000 Baht. But hard to get now because there is no new supply coming from China.

The best air purifier for reasonable money is made by Philips.

 

This is according to reviews by European specialist magazines.

 

You can pick one up in Powerbuy for 4800 Baht, for rooms up to 49 sq metres. Central in Cent Fest sell a more expensive model for bigger rooms, prices start at 7999 for a room up to 69 sq metres.

That kinda depends... Generally, ideally, you'd want a purifier for each occupied enclosed/separate space. For example, if you have a combined kitchen and living room area, you can think of that as one space needing one purifier.

 

But if you've got a bedroom that's closed off by a closed door, and have an air purifier in the living room, the living room purifier isn't going to help the bedroom much, especially if the bedroom has windows or doors that will leak air from the outside.

 

Of course the other factor to consider is what rooms/spaces you occupy at different times of the day or night. For example, you probably want an air purifier to clean the air in your bedroom at night. But if the bedroom is going to be unoccupied during the daytime hours, you don't need a purifier there and/or can close the doors to that room and leave it unpurified during the day.

 

Air purifier units generally are reasonably portable. So one way some people might handle the situation with one purifier is to place it in the living areas during the daytime, and then move the unit into the bedroom at night time. Or, some people have two purifiers, one for their living area and the other for their bedroom, and turn them on/off as needed.

I assume you're talking about a unit like this one:

Whether it's suitable for the OP depends on just how much space he needs to clean at any given time. Generally, you're supposed to buy a unit that's rated for a space that's larger than the actual area you need to clean.

That's what they say. And to make it interesting there are four standards of measurement. All quoted on the Philips air purifier box, which is how I found out. They are all wildly divergent. So according to one the air purifier is good for 20 sqm, using another it's good for 49 sqm. Depends which standard is used. That's why Philips showed all four.

I've been confused about that coverage range when looking at Phillips purifiers. But because I've never owned one or gotten serious about that brand thus far, I've never gotten into the nuts and bolts of which of their varying calculations is the best/most suitable one.

 

This is a recommendation on that general subject I came across lately:

Me too. At first I thought because it said the 'series' can clean 'up to' 49 sq m that there were models with different capacities. But turns out they meant according to the four varying standards for calculating clean air. Only when I got the box was that clear, and then only after a double-take.

 

So different organizations use very differing ways to calculate how much air cleaning is required in a room. For example:

 

The Philips AC1215, currently sold by Central for around 7900 Baht claims it is good for rooms up to 677 sq. ft. But that is based on the NRCC guidelines. Who the hell's the NRCC? It's the National Research Council of Canada.

 

To their credit, on their own packaging Philips also mention the AHAM standard, according to which the purifier is good for 222 sq.ft. A whopping three times difference to the NRCC. AHAM is the Association of Home Appliance Manufacturers of the USA.

 

Then there's the British and Japanese standards which are somewhere in the middle with 313 and 333 sq ft for this model.

 

Anyway I have a living room of 8x4 m and huge ceilings of 3.80. Even so this would put the sq ft total still well below the most stringent AHAM standard figure of 222 sq ft.

 

The key is that it's not square footage but cubic footage that matters, ie including the size of the ceiling. Most people just go by length by width which is not sufficient.

 

Anyway the AC1215 has clean air delivery rate of 270 m3 per hour! Even with this huge living room with super high ceilings, that is open plan on one side I still notice this Philips air purifier makes a huge difference, you can literally feel the difference.

 

Of course the downside is that it makes me now even more sensitive to dirty air outside the house. Since I'm used to such clean air inside the house now, lol.

Get the Ziaomi Mi Pro. It serves up to 500sf. I have one in the LR, and it works well. I have an air meter, so I test it. It also has a built in air meter, which displays the PM 2.5 - You will probably need two. The top reason for these units, is the low cost of the replacement filter. 600-800 baht. For 5 or 6 months use. Most of the others have replacement filters at 1500 to 4000 baht each. That is the dirty little secret in this whole air filter business.

AFAIK, AHAM is generally considered the gold standard when it comes to such things.

The downside about the Xiaomi units is a couple things...

 

--up until the 3 series model, their prior so-called HEPA filters were less than True HEPA capability, slightly less...

 

--their design feature is to build the HEPA and pre-filter into a single unit, so you have to replace it more frequently than you would a regular standalone HEPA filter with a separate (much cheaper) pre-filter that you can replace more frequently as needed.

 

On my Sharp model that has the two separate filter units, I'd probably change the carbon pre-filter every couple months, for a price of maybe $10 U.S.  But by doing that, the more expensive HEPA filter, about 1400 baht for my particular unit, lasted close to 1-1/2 years...

I just bought a Sharp FP-J30TA-A and was wondering if any of you has experience with this one. Does the HEPA-filter remove any odors? I tried but at least cooking smells and such are not removed but on the official site it says it should, don't know if there is any difference on the different colours of the same model (J30TA-P, or B...). 

 

Basically what I don't understand is if the filter has any activated carbon in it (which is the one that is supposed to filter odors).

Best regards
