How Your Home’s Indoor Air Quality Controls Can Help People with Asthma

Wednesday, November 23rd, 2011

There is evidence to suggest that higher quality air can help keep asthma symptoms in check. While you can’t control air quality everywhere you go, you can be in charge of the quality of the air in your Clarksburg home. Take a look at how controlling indoor air quality can help ease the suffering of asthma symptoms.

One study at Johns Hopkins found that indoor air pollution plays a large role in increasing asthma symptoms, especially among children. Without getting too technical, essentially the study explains that there are particles in the air we breathe, including indoors. Aside from the standard mixture of oxygen, carbon dioxide and other gases, air contains these solid and liquid particles, which are essentially pollutants. Common household tasks like dusting and cooking can generate more of these particles.

When these particles get into the respiratory system, they can irritate the lungs, which triggers asthma symptoms. Since children spend about 80% of their time indoors, this is a very big deal.

To help this problem, there are ways to control and improve the quality of air in your home. One simple way to do this is to have filters with high minimum efficiency reporting value (MERV) ratings in your heating and cooling system. MERV ratings describe how well filters catch particles of certain sizes and keeping them out of the air—and your lungs.

The particles identified in the Hopkins study were as small as 2.5 microns, which would require a filter with a MERV rating of about 12 to catch. Higher MERV ratings mean more efficient filtration, but they need to be replaced more often. If you or child has asthma, it’s worth it.

For severe asthma or allergies, consider even higher-rated filters, like HEPA filters, which sport a MERV of 17 or higher. These will catch nearly all allergens, irritants and other particles that can make you sick.

Sources of Indoor Air Pollutants

Monday, November 21st, 2011

Indoor air pollutants are a major issue for lots of Damascus homeowners and while you may know the most common culprits such as pet dander, pollen, dust and smoke, there are a few other indoor air pollution sources you may not be aware of. Here are some that almost any home will have and simple tasks you can perform to reduce their risk.

  • Cooking Surfaces – Gas stoves in particular are a major source of Nitrogen Dioxide. To reduce the amount of this gas in your indoor air, make sure you have proper ventilation above or near your stove. A simple exhaust hood or wall fan will do the job.
  • Insects – Roaches in particular are a major issue.  Their droppings, saliva and dead body parts can significantly increase the risk of health problems like asthma. Many other insects produce allergens as well, though roaches are worse because of their size and the nature of most infestations. Avoid using roach killers however. Prevention is better than extermination both for your indoor air quality and for the general health of those in your household.
  • Dust Mites – Dust mites are different from insects because they are so small (and are technically arachnids). They like things like your drapes, upholstery and carpet. They also like high humidity levels so if you can keep the humidity in your home low, they will be much less of a nuisance.
  • Asbestos – You’ve probably heard that asbestos is a carcinogen and should be covered or removed from your home. But do you know just how many places in your home it can be found? Asbestos is present in old insulation, spackle, pipe wraps and even some older upholstery. If your home is more than 30 years old, make sure it is inspected and checked for asbestos. If found, asbestos is usually isolated so it cannot fray and get into the air you breathe.
  • New Electronics – New products can have a variety of chemicals in them like phthalates that have a negative impact on the respiratory health of those exposed to them. These chemicals are emitted after a product is opened for the first time. With time their concentration will diminish, reducing the risk, but at first, make sure to properly ventilate the space and keep children away from new electronics or computers.

Chemicals, pollutants and other indoor air quality issues are numerous. To avoid a problem, make sure you investigate carefully to determine if your home needs additional repairs. And if you are worried about your indoor air quality, talk to your contractor about having an air cleaner installed in your home.

Types of Air Filters (and Happy Halloween Weekend!)

Friday, October 28th, 2011

Happy Halloween weekend from everyone at Tuckers Air Conditioning & Heating! We hope you have a fantastically spooky time! And since bad indoor air quality can be quite scary, here is some information about the different types of air filters you can get for your home.

When choosing an air filter for your home, there are many options. Each type of material is designed to capture a different type of particle to a different degree, so make sure you choose carefully based on the specific air quality problems your home has.

  • Disposable – Disposable filters are the simplest and least expensive option on the market but they are usually rated as low as 1-5 MERV and don’t last very long. These types of filters are usually designed for basic mechanical filtration to stop debris from causing problems for your furnace or air conditioner and are therefore not ideal for actual air quality improvement.
  • Fiberglass – Fiberglass filters are very common in almost all HVAC systems and are more permanent than disposable filters. They come in MERV ratings of between 4 and 12 and are highly efficient at capturing larger particles like dust, pollen and dander. These can be dangerous, however, as they fragment and can send fibers into the air.
  • Polyester – These have a higher resistance rating than most fiberglass filters and are therefore more durable against larger particles like dust and pollen. They also don’t fray like fiberglass and are more durable over time.
  • Electrostatic – Electrostatic filters have a charge to help collect dust particles and are usually made with multiple layers of polypropylene material.
  • HEPA Filters – This is a completely different category of filters and is designed to capture everything as small as 0.3 microns – well below the threshold most commonly provided by standard HVAC filters. They can be purchased for your HVAC system or as standalone filters for individual rooms.

There are a number of different filter types to maintain the air quality in your home. If you’re interested in getting the most out of your home’s air quality control system, make sure you do it with the best possible device available to your system. Contact a professional if you’re not sure what options will suit you best.

Control Your Comus Home’s Moisture – Humidity Is Key

Friday, August 19th, 2011

Most people don’t give a second thought to humidity until it is either much too high or uncomfortably low. And if you have a state of the art home comfort system, you’re probably comfortable inside all year long anyway. But there are several reasons to pay attention to the humidity level in your Comus home and take action if you realize that it isn’t providing the comfort level you’ve come to expect.

Many problems arise from excess or inadequate indoor humidity levels. For instance, a lack of humidity causes your skin and nasal passages to dry and crack, which is obviously pretty unpleasant. But air that’s too dry can also make the symptoms of allergies, asthma and colds worse. Anyone in your home suffering from these conditions will be much more comfortable when the right level of humidity is restored. Another great benefit is that the indoor air quality will no longer contribute to longer and more sever colds and flus in the winter.

Too much humidity is a problem too, though. It promotes the growth of mold, which is a big contributor to indoor air pollution. Mold spores are a big time allergen. The more moisture there is in your home, the more mold there’s likely to be. High indoor humidity levels also promote the growth of dust mites, another major indoor air contaminant and allergen.

Of course, you probably have a great indoor air cleaner in place to get all of those contaminants out of your home’s air supply. But if the air inside your home is too moist or too dry, it can actually make it harder for the air cleaner to remove all types of contaminants. Not only are you putting a greater strain on your body and immune system, you’re asking your air cleaners to work much harder, which can cost you money in repairs and filter replacements.

For all of these reasons, it’s important to put in a humidification system to maintain the overall quality of your indoor air. Plus, a properly humidified environment is simply more comfortable to live in. A humidifier can easily be integrated into your current home heating and cooling system, so you don’t have to worry about high installation costs or equipment compatibility. All you have to do is sit back, relax and breathe in the fresh air that your humidification system makes possible.

Some Facts From Rockville About Indoor Air Quality

Friday, August 12th, 2011

One of the least understood aspects of your Rockville home’s comfort system is the indoor air quality. Most people assume that once they have a good furnace and air conditioner installed, there’s nothing left to worry about. However, with the push in the last 20 years to reduce energy loss through poor insulation, most homes are sealed up tighter than ever before. This doesn’t just cause stuffy indoor air – it can actually lead to illness.

How Bad Can Indoor Air Quality Get?

Homes built in the 1980s were recommended to have one third of the ventilation of those built before. Today, the standards have returned to their original levels, but for many years, homes were built with poor ventilation and excessive insulation. The result is a space that holds the air in too well. Everyday contaminants and allergens like dust, pollen, pet dander, mold, or smoke cannot get out of your home and as a result, you can get sick.

In fact, some people even suffer from Sick Building Syndrome (SBS). This is when they feel ill constantly, with respiratory symptoms that have no root cause and are hard to diagnose. Often, it is because they simply breathe too many contaminants and too much stale air.

Fixing Air Quality Is Simple

The first thing needed to fix air quality is a good filtration system. Despite what many people think, simple filtration is not that expensive. There are big, powerful purification systems with advanced ionization units and UV lighting to kill bacteria and viruses, but most families are served well with a simple HEPA filter to remove things like dust, pollen and dander.

It’s a good idea to have your indoor air quality tested, however, just to make sure other contaminants are not present. High humidity can lead to mold growth, and poor ventilation can lead to exhaust or gas fumes in your home. A good carbon monoxide detector is recommended for the latter, but testing should be done to make sure nothing else is floating around.

Finally, make sure your home is properly ventilated. Standard ventilation tends to leak heated or cooled air outside, so many homeowners now opt for energy recovery ventilators. These systems have heat exchangers that transfer warm air between indoor and outdoor air.

However you want to fix your indoor air quality issues, know that there are plenty of things you can do with the help of a good filtration device and regular cleanings of your ductwork and vents.
