Client Testimonial

  • Residential Cleaning & Disinfection Services

    "Thanks again for the super professional service, your guys attitude and manners around my house and family were remarkable. I am not an easy customer but tonight I am surely a very happy one!"

  • Professional and Courteous Service

    Please thank your team for their hard work.

    They were professional and courteous and left the apartment cleaner than it was before! I look forward to contacting IAQ again for any aircon work!

    Thanks again.

  • The team just left about 10 minutes ago. Everything went very well- very professional. They were here early and had already checked in with the front office to get badges. Everything was left very clean after and they were very professional and efficient. I'm really happy- thank you.

  • I spoke with my husband who was here during the cleaning and he had nothing but good things to say about the your team!

    He said they arrived promptly and were very thorough from what he could see, both from inside the condo as well as going outside to the connecting unit. He was very impressed with their professionalism.

    Thank you very much !

  • A pest control product too

    Initially the first thing we noticed was those pesky mosquitoes suddenly disappeared from the office. We asked the makers if GermXit® had anything to do with this and found out that mosquitoes don't like Tea Tree Oil, it repeals them, so that was an added bonus. Clean air and no more mosquitoes.

  • Better than we thought !

    When we moved to a new office, everyone started to get sick. We asked for the air conditioners to be cleaned but that didn't seem to help. So we had GermXit® installed and hoped that would do the trick.  Over the next few months the sickness levels dropped and the staff started to comment that they hadn't had a cold or flu for a long time. Some of the staff have now bought GermXit® for their home too.

    Thanks GermXit®, it really works.

We all realize that the air outside can be very unhealthy and polluted, but most people don’t know that the indoor air quality (IAQ) of their homes, offices or work place can be even worse.

We all want to believe that our homes and work place provide a clean and healthy environment for our families and friends. A growing body of research, however, is pointing to very serious health consequences from both short term and long term exposure to particulate matter. Particulate matter is generated both inside a building and also brought in to the building from outside.

A problem occurs when our homes or work place is sealed from the outside air to increase heating or cooling efficiency as this allows build-up of pollutants from inside such as Volatile Organic Compounds (VOCs), radon gas, etc. Some exchange of outside air is necessary and also inevitable no matter how well a home is sealed. So, the particulate matter found in an indoor environments air will be a mix of particles from outside and those generated from within.

There are many varieties of particulate pollutants. Ones from outside include industrial sources, construction sites, combustion sources, pollen, and numerous others. Particles are also generated by all kinds of normal indoor activity ranging from using electronic devices, office equipment, cleaning chemicals, carpet, your pets, or even just getting up off the sofa or chair.

Any movement or vibration can create airborne particles – even air moving over an apparently clean surface will pick up particles. Airborne allergens, mould spores, bacteria, and dust mite/insect faeces are also present. A recent study by the Queensland Institute of Technology showed that even your trusty laser printer can be a high-level emitter of particulate matter. This is nowhere near a complete list of indoor particulate pollution, but what is truly disturbing is that many of these particles will lodge deep within the lung and remain there.

Radon gas has long been associated with an increased risk of lung cancer. The Radon itself is not actually that harmful, but it decays into radioactive daughter elements such as Polonium (the same element but different isotope was used to assassinate Russian dissident Litvinenko in London 2006).

According to the definitive study on Radon, BEIR VI from the National Research Council, these daughter elements “are electrically charged and can attach themselves to tiny dust particles in indoor air. These dust particles can easily be inhaled into the lung and can adhere to the lining of the lung. The deposited atoms decay, or change, by emitting a type of radiation called alpha radiation, which has the potential to damage cells in the lung. Alpha radiations can disrupt DNA of these lung cells. This DNA damage has the potential to be one step in a chain of events that can lead to cancer.” Using two different methods the report estimated 15,400 or 21,800 American lung cancer deaths occurred in 1995 due to exposure to Radon progeny.

If you live near a major roadway or busy street the particulate matter can be increased greatly by vehicle exhaust fumes. A tremendous number of studies show a link between this particulate pollution and cardiovascular disease, respiratory disease, and cancer. Studies of adolescent children show particulate pollution can retard lung function growth similar to cigarette smoking with predictable consequences for lung health later in life. The effects come from both long term and short term exposure. Studies show in the short term mortality rates from a variety of causes rise on days with high particulate pollution. Even if you don’t seem to be affected by high concentrations of particulates, please understand that the earliest symptoms to some long-term health problems like respiratory illnesses, or cancer don’t appear perhaps for many years after the damaging exposure takes place.

Indoor pets, especially pets that spend part of their time outdoors can significantly contribute to poor IAQ. All furry pets shed no matter what kind they are and they also produce dander. Brushing and wiping paws before letting them inside will help. Weekly bathing will keep shedding to a minimum. Owners that permit their pets to sleep in bedrooms or on beds (where hair and dander might accumulate) will be increasing their exposure.

Also, be aware that other uninvited guests in your home such as dust mites, other insects, or rodents will defecate inside. When their faeces has dried up it will become dust-like and possibly airborne, circulating through your home. If this dust is inhaled it can make family members ill.

There is no simple answer to improving IAQ and there is no way to completely clean the air unless you’re planning on living in a bubble. There are steps that can be taken to ensure you are doing everything to make your home and work IAQ as clean as possible. One of the first things you can do is to monitor your IAQ daily and to review the output, then determine what changes can be made to improve IAQ based on the output.
