I bought this Lancaster Air Purifier 157 in hopes it would help with my allergies + cigarette smoke in the house. Within 15 min,I could "smell" the difference. Actually,there was no cigarette smell at all. And now that Ive used the machine for the last few weeks,I have noticed a big difference in my allergies. Im not sneezing as before. Even picks up pet hair in the air. Im also not having to dust as much. It also doesnt require you to buy expensive filters. You simply vaccumm + wipe down the included filter,with a damp cloth. That saves you about 20.00-40.00! Its lightweight and be sit upright or or flat. It has 5 settings. Its kinda noisy using the #5 setting. But all in all its a great buy!
