In a quick answer, yes! According to studies done by scientists, over 50 million Americans suffer from allergies. With most people allergies are simply "seasonal" and they come and go as the seasons come and go. Their biggest problem is usually in the summer time when pollen is at an all time high. But a number of people experience chronic, year round allergies.

People with seasonal allergies often have symptoms such as itchy, runny nose, congestion, and sneezing. However, symptoms of non-seasonal allergies include: coughing, watery eyes, allergic conjunctivitis, and post nasal drip. It doesn't matter if you're a seasonal or non seasonal person, allergies are bothersome either way. Most of the air purifiers sold on the market today have built in independent ionizers that help in catching airborne particles.

When the air purifiers ionizer is turned on, a certain amount of voltage is applied to a series of built in "needles", which creates the electrons and discharges them into the atmosphere. When the electrons attack to the molecules, ions are formed.

Next, negative ions are dispersed into the room where you have the purifier placed, and attach themselves to dust particles, pollen, smoke and dander once they do this, they then form larger particles, which can then be easily trapped by your air filter. These particles can also fall to the floor to be vacuumed up later on. Negative ions are always present in our environment, wherever the air is agitated, especially around waterfalls, ocean surf, rivers and mountains. Positive ions are also present around us, in carpets, draperies and allergens in our home.

There are several different Ionizers (ionic) purifiers you can take a look at including:

Ionic Air Purifier Cleaner

One of the things I like most about the Ionizer, is even though the "design" is completely scientific the price is definitely NOT out of this world. These products are very affordable, selling on eBay for as little as $10 on up to $150. Personally, I wouldn't mind spending $150 on something that would make my life better, and easier to live on a day to day basis, would you? It would also be a good idea for you to check out reviews online. These reviews range from all sorts of ionizer brands, prices and "pluses" of the product!
