#prePaer AER System

Frequently Asked Questions

Bioaerosols are a diverse group of airborne particles that can include fungal cells and spores (mold), bacteria, algae, pollen, viruses, plant and animal debris (dander), and other combinations of biomolecules, ranging in diameters from tens of nanometers to millimeters. Bioaerosols can have a significant impact on human health, as the COVID-19 pandemic clearly showed.

They are microscopic, so they can travel long distances indoors. Being so light, they are affected by thermal forces, keeping them aloft within the breathing zone for prolonged period.

Our prePaer unit is designed to enhance indoor air quality by targeting airborne pathogens and contaminants (bioaerosols) like mold, pollen, bacteria, and viruses. It’s especially useful for environments with individuals who are immunocompromised, suffer from allergies, or are exposed to high levels of particulate matter. It provides a layer of protection that traditional HVAC systems or portable air purifiers might not fully address, particularly by filtering the air from the upper levels of a room, where contaminants typically circulate.
If you have suffered water damage or infiltration to home or office, you need to take immediate attention to remediate the risks associated with mold. So prePaer yourself with device that can do the job.
No, the prePaer unit is completely safe for infants and pets. It uses ULPA filtration without harmful chemicals, ozone, or external UV radiation, ensuring that it purifies the air without introducing any dangerous side effects.

Our prePaer system uses a proprietary ULPA filter, which captures 99.999% of particles as small as 0.12 microns, while still delivering powerful Clean Air Delivery Rate (CADR) of over 500.

ULPA stands for Ultra Low Particulate Air, and refers to a type of air filter that removes 99.999% of particles that are 0.12 microns or larger. ULPA filters are denser than HEPA filters and are used in commercial air filtration systems to trap very small particles. A human hair averages of around 70–100 microns.
Our current prePaer unit is built to provide a powerful sweep of indoor air. It has three speeds, On high, the “white noise” is unquestionably noticeable but certainly not harmful (<60 decibels). Keep in mind that the unit is designed to provide hospital-grade air scrubbing. It is also intended to cleanse a room before or after occupancy, in minutes. In home trials, occupants have run it extensively for prolonged periods—far in excess of the 45 minutes that we recommend to adequately cleanse a standard size room.
Sounds between 31–60 decibels are considered quiet. Sounds between 40–60 decibels are considered moderate and are not considered harmful to your hearing. 60 decibels is considered equivalent to a running washing machine. Our low speed operates at around 30 decibels, medium and high speed between 45-60 decibels.
Yes, it plugs into a standard 110/120-volt outlet, making it easy to install in most homes and offices without requiring special electrical adjustments.
No special installation is required. It arrives assembled, and the only thing that you have to do is place the filter carriage and filter on the top of the air intake. The prePaer unit is a plug-and-play device, portable and easy to set up in any room. Simply place it where needed and plug it in. If needed in another room, unplug, roll into the other room, and plug in.
Yes, the prePaer system uses our proprietary N99 filters that will need to be replaced periodically for optimal performance. This is a major advantage of prePaer. Our filters are single-use, and capture large amounts of dust, dander, and invisible particles such as pathogens and allergens, keeping them away from you. You want to be able to dispose of the filter quickly, easily, and safely before substances can grow on any filter medium and make matters worse.
The frequency of replacements depends on usage and environmental conditions, the seasons, and the particular sensitivities of the occupants. Take for example, in situations involving extensive water intrusion where tremendous amounts of invisible mold spores can be present, we would recommend changing the filter every two-three days until the sources of the mold have been remediated. Thereafter, we recommend weekly replacement for a month. It really depends on the state of the occupants and the attendant risks. Under normal conditions, we recommend filter replacement every two weeks if the dwelling or occupants are not suffering any particular problem.
Price depends on sale or lease; retail or wholesale. Please call for pricing.
No, the prePaer unit is not classified as durable medical equipment for Medicare or Medicaid purposes.

Yes, the prePaer unit is lightweight and portable, making it easy to move from room to room as needed.
The prePaer unit offers multiple speed settings, including a high-speed mode that can scrub the air in a typical room at least six times in 10-15 minutes, exceeding the CDC’s recommendation of 6 air turns per hour. A medium and slow speeds are included to provide quieter operations if the room is occupants.
At this time, white and black are the only color combinations that we offer.
Yes, the prePaer unit can be used in environments with high moisture, such as rooms affected by water damage or mold remediation, without losing efficiency. However, it should not be operated in standing water or where a visible water spray (rain or droplets) could get on the filter or the electrical cord.
Yes, the prePaer system includes a carbon filtration layer that helps remove odors, including those caused by pets and other organic pollutants. Using the prePaer, however, should not be a substitute for otherwise good pet hygiene.
Yes, the prePaer system’s carbon filter effectively captures and removes odors, cigarette smoke, and volatile organic compounds (VOCs) from the air.
Yes, it is safe and highly effective for classrooms, helping to create a clean and healthy learning environment by filtering out airborne contaminants that could affect students and staff.
Yes, it is safe and highly effective, and helps to remediate any “sick building syndrome.”
Yes, it is safe and highly effective. One of our customers, a medical clinic, deploys one unit in each exam and consult room, plus one in the lobby. In each exam room, the customer wipes down the device with a disinfectant, and runs it 10 minutes after each patient leaves cleaning the air for the next set of patients and providers. The lobby unit works on low all day, unless the clinic spots someone with a respiratory ailment, at which point the machine speed is increased and run at a higher level.
The prePaer unit is superior to other devices due to its use of ULPA filtration, which captures 99.999% of particles as small as 0.12 microns, its powerful Clean Air Delivery Rate (CADR) of over 500, and its ability to scrub air more rapidly than many comparable systems. Unlike other systems, it operates without harmful methods like ozone or chemicals, making it safer for continuous use.
It can work in any size room.
