The Best Ways to Enhance Whole-Home Air Purification

Learn about the best ways to enhance whole-home air purification

Clean purified air is desired more than ever, especially in our homes. Harmful particles and pathogens can pose a risk on our short and long term health. There is advanced purification technology that exists and is created with the intention of trying to improve whole-home air quality. Allergists and other medical professionals widely promote allergen avoidance as a way to improve health of sensitive individuals with respiratory diseases.

 

The premise is simple, reduce exposure to pollutants. Central Air Purification (CAP®) units from Abatement Technologies incorporate one or more effective and targeted air purification technologies for this purpose.

 

Mechanical particle filtration

 

Filters are assigned a minimum efficiency reporting value (MERV) rating between 1-16, the higher the rating the better the filter is at removing small particulates. A standard low-efficiency throwaway furnace filter rated at MERV1 or MERV2 is only effective for large particles.

 

CAP®100, CAP®600 and CAP®1200 series HEPA Air Purification Systems are equipped with MERV 4 first stage pre filters designed primarily to capture large, visible dirt and dust particles that are too large and heavy to be respirable, but can become a housekeeping issue when they accumulate on surfaces. The second stage pleated particle filters in these CAP® models capture smaller, visible particles that can easily pass through most throwaway furnace filters. The high-capacity 5” deep CAP®100 series second stage filter, MERV 13 is especially effective. 

 

Activated carbon filtration

 

The VAPOR-LOCK® activated carbon filters utilized in CAP®600 Series and CAP®1200 Series models capture airborne gasses, volatile organic compounds off-gassed from carpets, composite wood furniture and other materials in the home, and odors caused by pets, cooking or smoking. VAPOR-LOCK® filters utilize a process known as adsorption, in which the gas-phase molecules of the contaminants are attracted to and chemically bond to the surface of the carbon. 

Combining UV Germicidal Irradiation and Photolysis Technologies

Over time our homes endure different issues like persistent molds and fungal odor problems usually found in areas with high moisture or humidity levels like the damp, dark and dirty recesses of an HVAC system where organisms can thrive and multiply.

CAP® systems are equipped with our advanced, dual frequency UV plus lamp. Frequency one creates germicidal UV energy to irradiate and break down molds and fungi. The second frequency creates a controlled amount of trivalent oxygen for enhanced odor-neutralizing capability

CAP®100, CAP®500, CAP®600 and CAP®1200 Series Whole-Home Central Air Purifiers are equipped with germicidal UV lamp technology. Microorganisms are irradiated to high levels of UVGI energy each time they pass by the lamp as the air cycles through the central HVAC system of your home. All CAP® germicidal UV lamps are ozone-free. 

HEPA Filtration

The beauty of a HEPA filter is that its efficiency starts at 99.97% and actually improves as the filter loads. Because of the exceptional small-particle capture performance of CAP®600 Series and CAP®1200 Series models, these units are the most widely recommended for homes with family members who are asthmatic or have the highest sensitivity to respiratory allergens.

Things To Consider Before Comparing Airflow Ratings

 

Things to Consider Before Comparing Airflow Ratings

Why airflow ratings can be very misleading and the cheapest units are often the most costly.

No industry-standard airflow rating method

There is no standardized method that manufacturers use to rate the airflow of their air filtration devices. Different methods can produce widely varying and often misleading results, and make direct comparisons between brands difficult if not impossible.

Compare ‘Apples & Oranges’

The most overstated and inaccurate method used bases device airflow ratings on the AMCA “free air” blower rating, which is a test bench measurement of the airflow the blower can produce at various motor horsepower levels with no static resistance. Since actual peak airflow with the cabinet and filters in place is typically 50% to 80% lower, free air is essentially meaningless when it comes to rating the device itself.

Inlet or outlet readings with an air-straightening duct attached to reduce turbulence are far more accurate. This testing is generally done using a computing vane anemometer or pitot tube traverse to determine the average velocity (in feet per minute) and airflow (in cubic feet per minute) flowing through the air straightening duct. Attempting to measure airflow at non-laminar inlet and outlet openings is not recommended.

Peak airflow is only part of the story

Even when accurate, peak airflows can be misleading because they provide only a small part of the performance picture. It's often a mistake to automatically conclude that the performances of two devices are equal just because their peak airflows are similar. The airflow of all filtration devices drop off as resistance to airflow increases due to filter loading, external collars or flex duct. The magnitude and frequency of these losses; and therefore how frequently filters must be replaced to restore acceptable airflow levels can vary greatly.

Peak static capacity of the blower and filter dirt holding capacity are the main factors that determine 'real life' airflow and filter life. As a rule, a backward curved blower can move more air than a cheaper but less efficient squirrel-cage blower, due largely to its ability to operate at much higher 'tip speeds' and therefore overcome higher levels of resistance. This higher capacity, in turn, extends the useful life of the filters and can make a higher price but more efficient system far less costly to operate.

Build in a sufficient margin of safety

To compensate for airflow losses, users should build in a safety margin when estimating how many units are required to provide a given number of ACH (air changes per hour). If the objective is 6 ACH, designing for 8 or 9 ACH at peak airflow should be more than adequate to ensure sufficient airflow throughout the filter loading cycle provided that the peak airflow rating is reasonably accurate.

Reusable Modular Walls Are Becoming The New Standard

5 Reasons Reusable Modular Walls are Becoming the Standard for Temporary Dust Barrier Walls

Air quality in healthcare facilities is a worldwide concern. In March 2022 the U.S. Environmental Protection Agency released the            Clean Air in Buildings Challenge, a call to action for building owners of all kinds to take measures to reduce risks from airborne viruses and other containments indoors. This challenge encourages healthcare facilities, and others, to create an action plan for clean air, optimize air ventilation/filtration, and to showcase their efforts to building occupants and on social media. However, this challenge does not fully explore how maintenance and renovation efforts in healthcare facilities can negatively impact air quality.

Standard practice for healthcare facilities in the United States and Canada  is the requirement of a temporary dust barrier wall during renovation and maintenance operations. Depending on the amount of dust expected to be disturbed during construction activity, contractors may opt to contain their area with plastic sheeting, drywall or with the latest innovation - a reusable modular containment system.

Ultimately, patient safety is a priority for healthcare facilities worldwide but worldwide government initiatives are driving the need for proper containment with new regulations. . Construction can cause substantial dust contamination and scatter large amounts of fungal spores, like aspergillus, to patients without protective measures. Here are five reasons why a re-usable,  modular containment system is the new method your team should be deploying and why they are becoming the standard. 

1. Successful Containment 

Contractors should choose the best tools for the job to ensure Infection Control Risk Assessment (ICRA) compliance and superior infection control. They need a temporary containment system that seals, is easy to assemble and seamlessly incorporates other infection control equipment including HEPA level portable air scrubbers, HEPA vacuums and air pressure monitors. 

Truly successful temporary containment should also not disrupt the flow of the hospital. These re-usable, modular containment barrier walls provide contractors with a professional look that easily hides construction activities from patients and healthcare workers. To ensure clean visuals, some companies offer that the containment panels can be customized with the facility’s personal logos and graphics.

2. Maintain Pressure and Airflow

Contractors must have the necessary equipment to filter and monitor airflow within the containment area created by the temporary dust barrier walls. 

One of these necessary items would be portable air scrubbers with HEPA level filtration exhausted to either an existing indoor ventilation system or direct ventilation to the outdoors through an exit point such as a window or wall portal. Another would be a fixed or portable differential air pressure monitor that has visual or audio alarms, ensuring that the pressure and airflow is constantly controlled and recorded.

3. Reduce Hospital Acquired Illnesses 

Hospital-acquired-illnesses are of a significant concern for everyone who steps foot in a hospital, including patients, visitors, or employees. This is especially important for patients that are immunocompromised and susceptible to infection from the slightest exposure to dust contaminants.  Inhalation of indoor air pollutants from construction can negatively impact patients with chronic lung diseases but this can be prevented with effective dust control through containment units and barriers.

A modular containment system deployed before and during construction, where containment is properly ventilated and airflow is HEPA filtered, will prevent further infection and liability to the hospital and its workers. 

4. Reduce Costs and Speed Up Construction Timelines

The upfront fees and the time it takes for contractors to build traditional drywall barriers can be high, as the costs include materials, labor, disassembly and disposal of materials. Modular containment systems may appear more expensive initially but when you factor in the overall time savings at the build site in addition to compounded savings job over job, going modular far outweighs the cost of drywall assembly.  

A modular, adaptable containment system can fit into any job site and if it is reusable, you're not creating waste when it's time to move to the next job, compounding materials savings over time.

5. Promote Proactivity 

Throughout the history of healthcare construction new innovations have made a huge impact in patient and worker safety. Now, modular containment systems are the next generation of temporary dust barrier walls since they can get construction started with less labor, less time, and virtually less dust.

Since they are able to easily incorporate existing hospital construction equipment, they are simply superior to other temporary methods. Through standardization, the re-usable panels and doors are helping contractors to become more efficient and more environmentally friendly with each project.

How do I get started?
