5 Safest Cities for Allergy Sufferers

BOSTON ( MainStreet) -- Relocating to one of the communities on a new list of "America's Least Congested Cities" could be a real breath of fresh air for consumers who suffer from allergies or other breathing problems.

"I've been told stories of peoples' lives being infinitely changed for thebetter by moving to a new city and being able to breathe again," says Bert Sperling of Sperling's Best Places, which recently teamed up with Breathe Right Nasal Strips to compile the list. "Allergies can take a terrible toll on our quality of life."

Sperling analyzed the 50 largest U.S. cities for roughly a dozen congestion-producing factors, from ragweed and ozone levels to wind speed and other climate conditions that spread allergens.

Here's a rundown of the five communities the study found have the least problems with congestion -- along with a look at each city's local economy and housing market.

Home values listed below reflect asking prices on Realtor.com, the National Association of Realtors' official property-listing site. Price ranges refer to all houses, condos and townhouses listed on the site inside a given city and within about 20 miles of its borders.

Fifth-best city: Seattle
Median list price: $299,950
You'd think a place with so much greenery that it's nicknamed the "Emerald City" would have lots of pollen and mold, but it doesn't.

"Seattle had the lowest overall level of pollens and spores inour study, and low ozone pollution," Sperling says, although he adds that Washington state's largest city does have moderate flu incidence and allergy-medication usage.

The Emerald City is famous for its tech sector, which grew up around locally based Microsoft ( MSFT). Other based headquartered in or around Seattle range from Amazon.com ( AMZN) to Starbucks ( SBUX).

Boeing ( BA) also long called Seattle home, but moved to Chicago last year. The aerospace giant still makes a range of jets at two Seattle-area factories, though.

The 3.4-million-person metro area also hosts the busy port of Seattle, as well as the 42,000-student University of Washington and several smaller schools.

Realtor.com lists some 12,500 Seattle-area homes for sale, from a $29,900 one-bedroom condo in the city of Kent to a $26.9 million waterfront estate on tony Mercer Island.

Fourth-best city: Boston
Median list price: $319,900
The capital of Massachusetts has a low incidence of ozone and flu and slightly below-average pollen.

Sperling says those factors offset above-average levels of smoking and "a climate that can lead to respiratory issues."

In terms of the economy, Beantown hosts several well-known financial, tech and biotech firms, from State Street ( STT) to Boston Scientific ( BSX). The 4.5-million population metro area is also home to Harvard University, the Massachusetts Institute of Technology and other leading schools.

As for housing, there are some 12,100 Greater Boston properties listed for sale on Realtor.com. Prices range from $22,900 for a two-bedroom fixer-upper condo in the city of Lowell to $18.8 million for a 13.5-acre estate in the wealthy enclave of Weston.

Third-best city: Salt Lake City
Median list price: $198,900
"With its dry mountain climate, Salt Lake City has one of the best climatesfor freedom from respiratory issues," Sperling says.

Utah's capital has the lowest smoking levels of any city studied -- not surprising given the fact that the Mormon faith many residents practice bans tobacco use.

Salt Lake City also has the second-lowest flu incidence Sperling found, although residents do consume higher-than-average levels of respiratory medicines.

As for the local economy, Salt Lake City's major businesses include financial firm Zions Bancorp. ( ZION) and chemical manufacturer Huntsman ( HUN) (founded by the father of former GOP presidential hopeful Jon Huntsman). Other major local entities include privately held Sinclair Oil and the 23,000-student University of Utah.

Realtor.com has some 10,100 Salt Lake City-area properties listed for sale, from a $2,500 two-bedroom Park City, Utah, condo to a $49.5 million 60-acre estate that's also in Park City.

Second-best city: Miami
Median list price: $265,000
Despite its warm, moist climate, Miami actually has low levels of pollens and air pollution -- probably due to its location along the Atlantic Ocean, Sperling says.

He adds that the city also has low rates of smoking and the flu.

Miami has a widely diversified economy, although it has a heavy emphasis on tourism and businesses catering to Latin American countries and Hispanic-American consumers.

Corporations based in the Miami area range from Royal Caribbean Cruises ( RCL) to Perry Ellis International ( PERY).

The roughly 28,800 Greater Miami properties listed for sale on Realtor.com range from $6,500 for a foreclosed two-bedroom condo in Pompano Beach to $60 million for a 1.8-acre estate on exclusive Indian Creek Island in Biscayne Bay.

No. 1 least-congested city: San Francisco
Median list price: $599,000
Sperling says San Francisco "takes our top spot for freedom of congestion because ozone pollution is low, pollens are moderate, smoking is low and the use of congestion medications are the lowest for our study. The Mediterranean climate is dry and mild, and even the rate of flu in San Francisco has been well below average in recent years."

The City by the Bay has a diversified economy, with a heavy emphasis on tech and financial firms. Companies that call the San Francisco area home range from search-engine giant Google ( GOOG) to banking powerhouse Wells Fargo ( WFC). The 7.5 million-population metro area also hosts 25,000-student San Francisco State University and several other schools.

As for housing, Realtor.com has some 7,800 San Francisco-area home listings, priced from $30,000 for a one-bedroom home in Richmond, Calif., to $45 million for the newly build Villa Belvedere estate on exclusive Belvedere Island.
