RabbitAir BioGS SPA-421A

We like the fact that it is very silent, consumes very little energy and comes with features you’ll only find on premium air purifiers. We believe this is an excellent buy for those with mild to moderate allergy problem.

The is a solid air purifier for everyday use provided you don’t have any serious smoke, odor and molds problem. If peaceful sleep is a major concern, this is one of the machine you should consider. But it is not cheap to own or maintain.

With only 1 filter, this machine is cheaper to maintain than it’s bigger siblings. But negligible amount of carbon in the filter means that it will not help much with odor or smoke problem.

There’s no doubt that this is a good machine for your small room. Unfortunately, we think it is quite expensive to own and maintain. If money is not an issue for you, this is one of the air purifier that you should consider.

If you don’t care about noise, style and ease of use – but need a powerful machine that could help reduce odor, smoke and harmful gases, consider this one. But if you need a balance between the two, keep looking.

AllerAir 4000 Exec

It doesn’t come with all the convenience of modern air purifiers – things like auto timers, remote control or filter replacement alert, but the performance is so strong, some people simply don’t care. If you don’t mind having an ugly but very powerful machine to clean your air, consider the Exec 4000.
