A decent air conditioner

It seems to work great! It's a little big for our space but it moves well. The hose is also quite large so once you have it in place, it isn't that mobile. I bought it for the office and so far it's working beautifully.

I just bought a home. It's an old home and the AC is old as well and doesn't heat nor cool. For the same coast that it would take for someone to just come out and look at my AC, I bought this instead. It does a pretty good job. I just close all the bedroom doors and only cool the main common areas and my home is open enough that it covers pretty good. I'm just limited in where I could locate it but that has to do with the window locations of my house, not the unit. It has an adjustible insert to go into a window and hook up the exhaust hose. I use a fan to pull the air out of the dining room where it's located into the living room. 14,000 BTU is support for about 500 sq.ft. and I have it cooling about 700 sq.ft.

We do not have central AC in our older home, and we use this to move cool air from the main area into the kitchen, which is a dead-end with no circulation. It does the job very nicely. I do not think the noise is excessive; all fans make some noise - that's just how it works - and from the reviews, you'd think this little fan is noisier than most, but that has not been my experience.

There is a template included for mounting, and installation is a snap. The cord is nice and long, so no issues there.

I gave it four stars instead of five because lacks a reverse switch and the cord placement could be better. Reversing airflow means hanging the fan in reverse, and the cord placement is awkward because of this. I would still recommend this unit, we've been very pleased with its effectiveness.

So far I've only used it a few times but it's doing the job well. The fact that it's an AC/Heater and Dehumidifier in one unit is cool. Now I haven't tried it yet in really hot weather...so I'm withholding final judgement.

This unit has me pretty impressed, the only thing that knocked it down to four stars is the price. But, that being said, I was expecting to be disappointed by it's cool air humidifier when it's actually keeping the room just as warm and humid as a vaporizer (but maybe not so extreme).

The back of the unit houses the water reservoir that holds two gallons of water and you need to refill it approximately every 8 hours, depending on your humidity setting.

The air purifier works pretty well, too. I notice it get stuffier in the bedroom unless it's on.

One big drawback is if the reservoir runs dry the entire unit goes into sleep mode if you have it set to the hybrid setting. I'd still rather the air purifier be on, even if the humidifier can't be.

This air purifier has some things going for it and a few things holding it back. It is fairly compact and does not take up too much room on a night stand. The intake and output configuration is set up for optimal performance for placement in the corner or near a wall. Most air purifiers place the intake at the rear and output to the front. This is not very efficient if the unit is placed near a wall. This unit draws the air in from the front, filters it, then releases it upwards. I also like that the ionizer can be manually turned off. This filter would be perfect except for a few things. First, it is loud. It would be nice to be able to use it when I'm sleeping. Second, the filter door does not lock into place. The quality control on the clips that hold the door on is poor. So far it has been doing the job in a 12x12 room.

I was kind of expecting this thing to blast clean air like no one's business. Well, it does the clean air part. But air flow is rather slow. It's definitely not intended to keep you cool in the summer or anything like that. It keeps the air smelling fresh though, and for the price of this unit, I can't complain. I also like that it has a filter piece that doesn't have to be replaced with a new one, you can simply wash it off and go on with your day. I've enjoyed it.

This is a good quality portable a/c.  It was easy to set up and easy to start using.  It was used for 2 months this summer and worked very well.  I gave it a 4 star rating because I don't think the square footage rating is accurate.  I think 350 sq feet is more like the max coverage area.  I don't think it would be able to cool over 500 sq feet.

I bought this for my upstairs bedroom which I have converted into a small office at 12x12. I work from home about 1/2 of the time so I needed a way to maximize energy efficiency and just cool my immediate area (instead of running the central air and cooling 5 other unoccupied rooms). The window I have in that room is a sideways siding window so I decided to get a portable a/c. This a/c does a decent job of cooling the 12x12 room but man its loud. One thing that bugs me is that I have to turn the unit off when I make a call so I can hear the other person. Its definitely not as quiet as the window unit I have in my bedroom.

I don't think this unit would actually cool a medium to large room. You probably wouldn't want it for anything over 250 square feet. Setting the unit up is easy since it can roll and I had no trouble putting it up in less than 15 minutes. The hardest part of the setup was getting it up the stairs, it is pretty heavy. The remote feels a little cheap but seems to work just fine. The hose produces some heat but the unit is far away from me that I don't feel the heat. The vent is semi directional and can move side to side but not up and down. Overall its a decent unit if you don't mind the noise. If noise is an issue, you should probably avoid this unit. Hope this helps!

Not bad, just not very good either.
Unit can be a bit loud, especially in smaller rooms.
Cools relatively well, however, takes a little while to get there.
for the price, you really can't go wrong. We will see how the longevity is after a season or two, but for now, it's doing it's job.

I live in Seattle. There are only a few days per year that one needs or wants air conditioning here. Assuming you do not live on a very busy highway, most of the year here, you just open your windows.

I got this portable air conditioner because the windows of my rented condo will not hold a window air conditioner. This product got a very high rating on Consumer Reports.

The air conditioner has a hose so that you can drain the condenser if necessary -- I have never had to drain the condenser.

As noted the portable units just are not as powerful as a window unit, so if one had windows that would hold an air conditioner, I would tend to get one of those.

The unit was powerful enough that it cooled both our bedroom and our front room. I intend next year to buy a second one so that we have one just for the bedroom -- I think it could more effectively cool our front room if it wasn't trying to cool both rooms.

As noted in other reviews the hose gets very hot and so throws heat back into the room. I would use the detailed instructions in one of the other reviews detailing how to insulate the hoses to prevent having them kick heat back into the room.

Also the piece that fits in the window, it is long and narrow, but not quite long enough. We could extend it with a little balsa wood or something else to completely cover the window.

If you have a window that will fit a window air conditioner, just get one of those. Use Google to determine the BTUs for the space you want to cool -- you need the right number of BTUs to cool your place.

If you are a home owner or own your condo/apartment, consider paying to get a wall unit and get someone to install it.

If your windows will not hold a window unit and installing a wall unit is not an option (you are a renter, not an owner), then get one or two of these portable units.

The cooling station does the job as advertised earning 4 stars, it does indeed cool my laptop down noticeably and is relatively quiet to use. The sloping and the extra USB can be a nice addition if you need it.

The 5th star is not earned for several reasons.

a) To turn the fans on and off, you must reach behind the laptop to do so, which is not really convenient.
b) The LED lights are extremely pointless and I feel would generate heat (even just a little) which counters the goal of the pad. You cannot turn off the LED's for the fan, but there is a button for the center LED which is also pointless.
c) The fans are not guarded well on the bottom, which again is not a huge problem, but when moving the pad, I have gotten clipped by the fan several times when trying to readjust the pad.

Overall, this was a great purchase, but there are things that could make this a little bit better as well.

It is like having a constant cool breeze. I would recommend this for areas that are on the fringe of needing A/C but you could get away with not having one. This thing will take the edge off on a hot day. And it has great features like "swing" which moves the fan 60 degrees back and forth, left to right, to cover a larger area of the room. I like just directing it all to me when I am working by the computer though. It is portable so you can move it into the bedroom at night.

I'm pretty darn happy with this thing. Uses much less energy than an A/C.

Updated: This unit didn't really hold up in the long run for me. Broke and stopped cooling as well as when I first got it. Was hard to keep clean as well.

It made it through one winter, but I'm not sure if I will use it again next year if I can find another option.  It did well enough keeping the main floor of my home (1100 sq feet) relatively well hydrated, but would run what I considered a lot on the 2nd fan setting to maintain a 40% relative humidity level.  My home was built in the 70's, is of brick construction, and has all new Pella double-hung Low E windows, so is of better construction and "tightness" than many homes of similar age.  Also, the motor / fan developed a "buzz" about 5 weeks into use that is extremely annoying on the 2nd fan setting, so I typically run it at level 3 during the day, and 1 in the evenings / overnight.  Finally, on those dry winter days under 20 degrees, you will be filling it daily, although it is pretty easy to fill.  Despite the minor annoyances, it did make a noticeable difference in the comfort level of our home (less itchy, staticy time at home) so it earns 3.5 stars.  Also, a tip for the filters - flip them every few days, and keep an extra one handy.  After two weeks, put the fresh filter in and soak the used filter in a plastic tub with a cup of white vinegar and water overnight, then hang it on a drying rack so it can be reused.  We had no fungus/mildew or bad smells all year and having refreshed filters definitely helped the unit perform better as well.

I am very sensitive to warm temperatures but even more sensitive to huge electric bills when the central AC is working 24/7 so putting a decent tower fan near my AC vent is my best solution. And while it isn't an air conditioner it cools the room in a jiffy. The remote is key for me too, and this one is pretty user friendly. Was not the easiest thing to put the stand together, but anybody can do it eventually. I just remember a few curse words on my part.

The main negative is that these fans have a pretty short life span compared to other appliances I buy in this price category. I am on the page looking for a replacement because the one I bought a few years ago is about to crap out, making chirping, whistling noises and taking a while to oscillate after turning it on now that is terminal. This upcoming purchase will be my fourth tower fan in 5 or 6 years.  2 years seems about the average life for this product in my house.

I've been using the NewAir AH-450B for about a month and it meets my expectations. Upon unpacking, I was skeptical how effective it would be due to the thin-ness of the fins.  This isn't a bulky unit like other oil filled heaters; there doesn't seem to be much oil inside to heat.  However, it does kick out a good amount of heat and makes my unheated family room comfortable. I guess it's all in the engineering.  To avoid unpleasant smells, before first use run the unit outside on high for a few hours to burn off whatever seems to be coating the unit from the factory. The unit made some crackling sounds the first few uses but they disappeared over time. The thermostat and heat control works well. Be aware that it does draw some amperage so avoid using on electrical circuits with other high amp appliances like microwaves or vacuums.  Overall, I'm pleased with the product.

I bought this AC for my sons room because it gets extremely hot in the spring and summer. The installation of the parts was easy and pretty self explanatory because the directions are not the greatest. His room is not that big and set at the lowest setting he would need to use his winter comforter at night. Make sure you seal your window correctly so you are not losing your cool air. Also, the 4ft hose is short and you will not be able to put it too far from the window. The hardest part was attaching the hose to the inlet and outlet pieces after that it is plug and play.
