Indoor Air Quality During Construction

Construction Site Flush-Out Services

Rapidly eliminate construction-generated airborne particulates, VOCs and odor.

Interior Construction Produces: Dust Particles, VOCs, Bio Aerosols...

PURE Air Purifier Installation( Classified as a Class II Medical Device by the FDA )

Results - End users can inhabit the space sooner, without negative impacts to comfort and health.

WHAT WE DO ?

Large Office Spaces :

During Construction: Continuously flush the air through PURE’s patented a mixture of carbon, zeolite, phosphorus saturated filters + the patented EMF HEPA filtration machines dramatically reduces VOCs and captures and kills 100% of air borne particles Bio-aerosols.

At Construction End and Furniture is Moved in:

Increase the amount of Carbon/Zeolite air treatmentOvernight High Ozone Shock TreatmentDeep cleaning and Application of PURE DEOAddition of Tea Tree Oil in AC Units

Hotel Rooms and Residential:

48 hours of Air Flush Out with PURE patented filtration units.Carbon/Zeolite air treatmentOvernight High Ozone Shock TreatmentDeep cleaning and Application of PURE DEOAddition of Tea Tree Oil in AC Units.

Hazardous Ultra Fine Dust Particles – can float in the air for weeks

Cutting & grinding of wood, plywood, laminates, plastics. plaster, insulation , stone, tile…

Sanding & drilling of drywall, wood, metal, plastic, cement, spray painting and lacquer finishes.

Ultra-Fine Particles 0.01 to 5.0 Microns floating in the air for weeks.

VOCs...volatile organic compounds ... chemical odors

Formaldehyde – plywood, insulation, gypsum board, furniture, cabinets.

General VOCs – glues, sealants, paints, thinners, carpets, wall coverings, laminates, plastics, furniture, insulation, chairs, tables etc.

VOC Gases – Easily spread through the space and difficult to contain. Off gassing can continue for months.

Bio Aerosols

Molds, fungi, bacteria, virus can easily grow in humid conditions.

Problem : Dust Particles, VOCs, Bio Aerosols...

short term - asthma attacks, allergies, itchy eyes, runny nose, skin rash, headaches, nausea…. uncomfortable, unhappy staff

long term – linked to heart disease, stroke, respiratory problem.
