Air Quality

Automated Air Quality Management as part of unified Smart Home solution has quickly become a priority for many. Lexi provides a suite of solutions that are integrated into the overall offering.

Benefits of Clean AirFiltration

Bad Air can mean many things as you can read below.

The primary benefit of having clean air is that you, and anyone sharing the space with you, do not get sick nearly as often.

Getting sick can mean a lot of things: contracting COVID, or the flu, developing heart issues or even be inflicted with cancer. In addition to not developing an illness, there are also some real meaningful upsides to clean air.

The Dangers of Breathing Bad Air

The Problem with Indoor Air: Respiratory Illness are primarily transmitted indoors & Viruses & Bacteria "Hang" in Indoor Air.

80% of COVID-19 cluster outbreaks... were in the home. All identified outbreaks of three or more cases occurred in an indoor environment, which confirms that sharing indoor space is a major [COVID-19] infection risk.


COVID & Air Quality

After extensive research, the overwhelming evidence supports aerosol transmission of COVID-19. Contact tracing shows that, when it comes to COVID-19, being outdoors is 20 times safer than being indoors, which argues that aerosol transmission is much more important than droplets; outdoors, there’s plenty of air in which aerosols can become diluted; not so indoors. Superspreading events occur almost exclusively in indoor locations and are driving the pandemic. These observations are easily explained by aerosols, and are very difficult or impossible to explain by droplets or fomites.

HEPA filters are designed to trap aerosols, and thus are well suite for removing aerosolized COVID from indoor air.

HEPA Filters

HEPA Filters remove nearly all viral & bacterial particles from the air. Our HEPA Filters are H13 medical grade which means they remove 99.95% of particles.

UVC Light

The Lexi Smart Air Purifier includes a UVC light. UVC, is far more powerful than UVA or UVB, the components found in sunlight. Research has shown that low doses of UVC inactivated 99.9% of airborne coronavirus.

Particle pollution — also called particulate matter (PM) — is made up of particles (tiny pieces) of solids or liquids that are in the air.

These particles may include:

Fine (smaller) particles, called PM2.5, are more dangerous because they can get into the deep parts of your lungs — or even into your blood.

COVID & Particulate

In the Netherlands, researchers identify a correlation between particulate pollution and COVID-19 cases, hospital admissions, and deaths. “What I was struck by was this really was a strong relationship,” coauthor Matthew Cole, a professor of environmental economics at the University of Birmingham in the UK, tells The Guardian.

A previous study in the United States found that just 1 µg/m3 more fine particulate matter in the air corresponded to 8 percent more COVID-19–related deaths. The new study found that in the Netherlands, for the same increase in fine particulates, the death rate was as much as 16 percent greater.

HEPA Filters & Particulate Pollution

HEPA literally stands for "High Efficiency Particulate Arrestance". The Lexi Smart Air Purifier works in conjunction with our Smart Air Quality Sensor to automatically manage your air quality, including the critical PM2.5. When the Air Quality Sensor picks up higher levels of particulate, it instructs the Smart Air Purifier to increase fan speed for example.

Volatile Organic Compounds ?(VOCs)

According to the EPA, VOCs are 2-5X more common indoors than outside.

During and for several hours immediately after certain activities, such as paint stripping, levels may be 1,000 times background outdoor levels.

High levels of VOCs can cause permanent harm.

VOCs are released from many consumer products:
  • Cigarettes
  • Solvents
  • Paints and thinners
  • Adhesives
  • Hobby and craft supplies
  • Dry cleaning fluids
  • Glues
  • Wood preservatives
  • Cleaners and disinfectants
  • Moth repellants
  • Air fresheners
  • Building materials and furnishings
  • Copy machines and printers
  • Pesticides
Long-term health effects from VOC exposure include:
  • Nausea
  • Fatigue
  • Loss of coordination
  • Dizziness
  • Damaged liver, kidneys, and central nervous system
  • Cancer
Short-term health effects from VOC exposure include:
  • Irritation of the eyes and respiratory tract
  • Headaches
  • Dizziness
  • Visual disorders
  • Memory problems

VOC Detection

The Lexi Smart Air Quality Sensor will detect Total Volatile Organic Compounds (TVOCs) in your environment.

Our mobile and cloud reporting & analytics will provide continuous reporting of levels and our notification system will automatically alert you via text message if it detects abnormally high levels.

Removing VOCs with? Activated Carbon

The Lexi Smart Air Purifier includes an Activated Carbon Filter. An activated carbon filter removes VOCs through a process known as adsorption, not to be confused with absorption. During adsorption gases passing through an activated carbon filter are chemically bonded to the hollow surfaces inside it of the filter, trapping them permanently.

Formaldehyde is a particularly nasty VOC that even at very low levels can be quite harmful. When formaldehyde is present in the air at levels exceeding 0.1 ppm, some individuals may experience adverse effects such as watery eyes; burning sensations in the eyes, nose, and throat; coughing; wheezing; nausea; and skin irritation. Some people are very sensitive to formaldehyde, whereas others have no reaction to the same level of exposure.

Chronic exposure to formaldehyde may also cause general damage to the central nervous system, such as increased prevalence of headache, depression, mood changes, insomnia, irritability, attention deficit, and impairment of dexterity, memory, and equilibrium. Long term exposure has also been shown to significantly increase your chance of ALS. It can also cause cancer, and has been linked to an increased risk of asthma and allergies in kids.
