Review on Pure Enrichment® PureZoneTM Portable Purifier by Jennifer Franklin

This works well and is great for traveling. Keep in mind how small it is when deciding if it suits your needs. This is VERY low for a HEPA purifier. It works well but cannot move much air due to its size. For example, don't expect an entire hotel room to be filtered out. It will provide purified air in the immediate vicinity of its installation site. It runs on both AC and battery power, so battery life isn't an issue if you have an outlet. It can be noisy at the highest settings, but it's no louder than when you turn on a regular one-room air conditioner, so it wasn't particularly noticeable.
