My fiance has asthma and suffers from severe allergies – both seasonal and pet related. We have 3 dogs and she has suffered for years with asthma flair-ups because of them – to the point where she was constantly miserable, could not breath, and would need to take 2-3 doses of albuterol per day just to cope. Bedtime was especially difficult and it was extremely rare for her to not need the medication then.

We tried everything…doctor visits, allergy medications of all sorts, moving our bedroom to every room in the house…putting filters on our fans and A/C…leaving the windows closed or open…using a variety of (less expensive) air purifiers – both HEPA and Ionic. Nothing worked and she was in constant misery.

Enter the Minus A2. I was out of ideas and doing my Amazon homework about air purifiers, once again, when I came across this unit. It was expensive but I decided to spend the money and try it out. I could always return it.

It arrived quickly and well-packaged. In fact, everything about this product says “quality”. I set it up and ran it (I opted for the Pet Allergy extra filter) for a few hours that night while she was at work. As soon as she entered the living room she noticed the improvement in the air quality. We moved it upstairs and, lo and behold, she did not need to use her medication for the fist night in months! For 2 weeks now we have moved it between downstairs during the day and upstairs at night and she has only had to use the pump 1 time – and that was after she cleaned the house for 4 hours one day. This product has been truly amazing. I really thought she would never find comfort in our house again but things are so much better now and it has made everything about our time in the house better.

We have yet to try it out in full allergy season but I will be buying another one before then so the whole house can be covered all the time. This was literally a saving grace type of product for us and I could not recommend it highly enough. I cannot guarantee it will work as well for others as it did for us, but we are highly satisfied.

Just as an aside…we tend to run the product on medium or higher speed. It makes a bit of noise but we like the white noise at night for sleeping so we leave it set there. I cannot vouch for how well it filters on the lower speed but the Low/silent speeds are very quiet indeed – if that is what you need. The lights on it are bright but we turn off the mood light and face the unit towards a wall to deflect the power light. I am a light sleeper but the added light does not bother me.

I hope this helps and we highly recommend this unit.

I have this and the the austin air hm-400. I actually like the hm-400 better because: 1) its louder, but it has a white noise sound (like an HCAV unit makes). The rabbit has a motor sound. 2) I dont believe this actually filters much on low or quiet.

The major selling point for me on this was the claimed noise level. I wish I had a DB sensor, because i can still clearly hear it at night if its in our room (on quiet!). I can hear the motor spinning. Maybe its a problem with the unit, who knows, but i thought it was suppose to be inaudible on quiet.

I have a strong feeling that the cubic feet estimate is not realalistic unless its on high or turbo which is too loud for me. I didnt notice any difference in air quality with this.

The mood light is stupid, but at least you can turn it off.

The charcoal filter is also a bit silly. They say its washable, ha! Show me how washing it takes out the smell. Be prepared to buy a new one a few times a year (30 a pop)

Pros:
Great looking
Energy star
electronic
fairly quiet

cons
price
doesnt filter what it says it does unless its on a higher setting
charcoal filter will be expensive to replace frequently.

All in all, this game is a quick, dirty port of a wonderfull PC game. A lot of homebrews are way better than this and are free !

So if you enjoy tower defence games, i suggest to stick with NinjaTown (wonderfull gem, but sadly too short) until another one came out.

If you’re buying this for something new, you’re likely to be disappointed. But as a new way to play the same game, it’s a very faithful version of the game, with a few slight twists on how the game works.

Definitely one of the best TD games out there. Now if only they would bring a version of Gemcraft to the DS…

P.S. Don’t listen to the guy above me. Read the comments I made on his post.

These were heavily reinforced massive concrete and steel structures designed to provide both platforms for the flak guns to fire against Allied air attacks and also to provide bomb shelters for the civilians seeking protection from those air attacks.

Whereas most bomb shelters and military bunkers were built into or below ground, these Flak Towers had to be built above ground. Their size and structure made them very unique and thus a fascinating thing to learn more about.

Michael Foedrowitz does an excellent job of detailing Germany’s Flak Towers. There are plenty of photographs of each and he recounts the history of their construction, use during the war, and their eventual demise – or continued use to this day.

This is a little covered historical subject and this book, slim as it is, does a good job of providing a great wealth of detail on these wartime creations.
