>>> now on "today's home", allergy proofing. wet winter weather leaving us with a worse than usual allergy season. lou, good to see you.

>> nice to see you as well.

>> a bad season?

>> everybody talks about. this i've heard from allergists and the companies that make all of the allergy medicine, the fact that these mild winters we have, we haven't killed a lot of that pollen and as we warm up, people are already feeling the effects. certainly those over-the-counter med since, they can prescribe those type of medicines, they're very helpful. we have seasonal allergies in my own family, but there are things you do to help the indoors, which is two to five times more polluted than the outdoor air.

>> things you can do.

>> duct work has holes in it. this is an example of a lot of holes in it. but all of these gaps and seams that are in duct work have holes and gaps. when the air is flowing through the duct work, these gaps can pick up dust and debris and flow through. there's a process called aeroseal. it's a professionally installed system where they clean the duct work, then they run this polymer through. it can seal a hole up to 5/8 thick -- or an opening in the duct work, just by inside the duct work going through there. the system runs more efficiently, you save money on your energy bills and the indoor air quality is fantastic. $1,200 to $1,500 on average.

>> that's one you want to call the pros on. something you can do yourself, change the air filters .

>> these are the filters, the inexpensive ones do nothing to help the air. they are just designed to protect the blower motor. these flepleated filters, it grabs ten times more particulate. you will be amazed at the indoor air quality improvement. some people say you shouldn't use these because it restricts the air flow in your furnace. that's just not true. if you keep them changed once they get dirty, your furnace won't do the difference but your nose and allergies will.

>> how often do you change those?

>> it depends on where you live, but on average every two months.

>> this is a whole house air purifier .

>> this is from carriers. there's a lot of different manufacturers that make this. this is their infinity air purifier . what's unique about this is it that it actually kills pathogens. literally, influenza virus, their filtering system inside here gets changed every six months. when this thing is installed properly and you're allowing that air to circulate through your home, it will make people breathe easier. this unit is about $1,200 installed. people that use them and have these types of units installed in their homes swear by them.

>> and where would you put that in the home?

>> this is next to your furnace, part of that whole larger system.

>> this is something i hadn't seen before. this is part of a u.v. light system.

>> this is a do it yourself item called sword fish . the u.v. light will kill 99% of the particulate that flows through it. this is very popular. until recently it was only a professionally installed item. you may seem like oh, i don't want to try it, it's actually not that hard. it's drilling a hole in the duct work in the right spot and plugging it in. these bulbs are replaceable. this unit is about $140.

>> a hardware store ?

>> hard we'ware store and home centers will carry it. a room purifier. dave wakes up and can't breathe in the morning. this one actually senses the particulat nerve trvegs particulate in the air. down at the bottom is this blue air sense. they range anywhere from $299 to $479. if you let them run and circulate the air with the fan, you will inprove your indoor air quality .
