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 found that the number of illnesses dropped around 80%. Further the nasty smell that dominated disappeared.”

Case Study – Monash University School of Applied Sciences Report

 

Lab Studies Biocidal Activity of Airborne Tea Tree Oil in a Model HVAC System

The purpose of the test was to determine the effect of vaporized tea tree oil on organisms commonly found in HVAC systems. It has been commonly assumed that heating ventilation and air conditioning systems are a source of indoor bioaerosol contaminants. Monash University scientists were asked to study the efficacy of tea tree oil vapor – airborne tea tree oil – in a model AC duct system. Numerous studies[1] had previously shown the effectiveness of tea tree oil in controlling various molds and biocontaminants when applied directly but this study proved that tea tree oil is highly effective when dispersed in the air as well.

Test procedure

A model air duct was set up to allow for repeatable experiments. Test “filters” were contaminated with E.coli bacteria and a common yeast fungi called C.albicans. Various tests were conducted exposing the contaminated filters to airborne tea tree oil generated by airflow over the GermXit gel and also control tests without tea tree oil in the system.

Conclusion

Results clearly showed that tea tree oil is evaporated into the system by airflow and that airborne tea tree oil is effective in controlling microorganisms by being dispersed in the air.

“Under the conditions of the experiment, [GermXit]* gel had a measurable biocidal effect on E.coli [and C.albicans]” – Monash University Report[2]

Previous to this scientific study the effectiveness of tea tree oil had only been laboratory tested using a direct contact method with the organism[1]

“Furthermore the present study has demonstrated that [GermXit]* gel has the potential to be a useful decontamination agent in HVAC duct systems– Monash University Report

การศึกษาวิจัยของห้องปฏิบัติการ  ในการทำงานของน้ำมันจากต้นชาในระบบทำความเย็นขนาดใหญ่ (HVAC)

วัตถุประสงค์ของการทดลองเพื่อหาผลกระทบจากการระเหยเป็นไอของน้ำมันจากต้นชาต่อสิ่งมีชีวิตที่พบทั่วไปในระบบทำความเย็นขนาดใหญ่ (HVAC) ด้วยสมมติฐานว่าการระบายความร้อนและระบบเครื่องปรับอากาศคือแหล่งของสิ่งปนเปื้อนชีวภาพที่เป็นละอองในอากาศภายในอาคาร      และนักวิทยาศาสตร์ของมหาวิทยาลัยโมนาชยังได้ทำการศึกษาถึงประสิทธิภาพของไอระเหยน้ำมันจากต้นชาที่กระจายอยู่ในระบบท่อปรับอากาศ (AC) การศึกษามากมายก่อนหน้านี้ได้แสดงให้เห็นถึงประสิทธิภาพของน้ำมันจากต้นชาในการควบคุมเชื้อรานานาชนิดและสิ่งปนเปื้อนชีวภาพเมื่อใช้น้ำมันจากต้นชาโดยตรง แต่การศึกษาครั้งนี้ยังพิสูจน์ได้อีกว่าน้ำมันจากต้นชามีประสิทธิภาพสูงเมื่อกระจายในอากาศ

กรรมวิธีการทดสอบ

มีการจำลองท่ออากาศเพื่อให้สามารถทำการทดสอบได้หลายครั้ง แผ่นกรองที่ทดสอบปนเปื้อนด้วยเชื้อแบคทีเรีย อี.โคไล และเชื้อรายีสต์ธรรมดา ที่เรียกว่า ซี.อัลบิแคนส์ ได้ทำการทดสอบหลายครั้งโดยใช้แผ่นกรองปนเปื้อนทั้งกับน้ำมันจากต้นชาที่กระจายตัวโดยการไหลเวียนของอากาศผ่านเจล GermXit®  โดยไม่ใช้น้ำมันจากต้นชาในระบบ

ข้อสรุป

ผลลัพธ์ปรากฏชัดเจนว่าน้ำมันจากต้นชาระเหยเป็นไอเข้าสู่ระบบด้วยการไหลเวียนของอากาศ และน้ำมันจากต้นชาที่กระจายตัวในอากาศมีประสิทธิภาพในการควบคุมจุลินทรีย์ด้วยการทำให้แตกกระจายไปในอากาศ

“ภายใต้เงื่อนไขของการทดลอง เจล GermXit® มีผลในการยับยั้ง
อี.โคไล (และ ซี.อัลบิแคนส์) ที่สามารถยืนยันได้
– รายงานของมหาวิทยาลัยโมนาช[2]

ก่อนหน้าการศึกษาทางวิทยาศาสตร์นี้ ประสิทธิภาพของน้ำมันจากต้นชาได้จากการทดสอบในห้องปฏิบัติการโดยใช้วิธีสัมผัสโดยตรงกับสิ่งมีชีวิตเท่านั้น[1]

“ยิ่งกว่านั้นการศึกษาดังกล่าวนี้ได้แสดงให้เห็นว่าเจล GermXit® มีศักยภาพที่จะเป็นสารที่มีประโยชน์ต่อการสลายการปนเปื้อนในท่ออากาศของระบบทำความเย็นขนาดใหญ่ (HVAC)” – รายงานของมหาวิทยาลัยโมนาช
