The fan powered unit draws air directly from the space, through a MERV rated filter, and discharges the clean air directly back into the space.  **Pandemic Ready Patient Rooms**  The pandemic ready patient room solution from Price and Antec Controls allows the hospital to build one room that can be used for either standard patient care or as an AIIR, and can change between operational modes at the touch of a button, a feature that may be sought-after post Covid-19.  For more information on Pandemic Ready Patient Rooms, [click here to view the full brochure.](https://www.priceindustries.com/content/uploads/assets/literature/brochures/pandemic-ready-patient-rooms.pdf)  **Dental Operatories **  Dental Operatory solutions from Price make use of engineering controls including high-volume source extraction1, HEPA filtration2, and recirculated room air to improve indoor air quality while maximizing contamination control and system efficiency.  For more information on Dental Operatories, [click here to view the full brochure](https://www.priceindustries.com/content/uploads/assets/literature/brochures/dental-operatories---new-construction.pdf).    Solutions for Retrofit Applications:   **Overhead Mixing System with Integrated Filtration**  **Option 1: Retrofit Existing Diffusers(**[**Filtered Diffuser Module \[FDM**](https://www.priceindustries.com/criticalenvironments/products/filtered-diffuser-module)**\]): **Retrofit filtration attachments include a 2", MERV 13 or 15 filter and a secondary diffuser face and are suspended directly below existing diffusers so that ductwork changes are not required.![](https://info.hoffman-hoffman.com/hubfs/image-png-Mar-31-2021-07-40-43-69-PM.png)  **Option 2: Recessed Diffusers with Integrated Ceiling-Access Filters(**[**Filtered Diffuser Module \[FDM**](https://www.priceindustries.com/criticalenvironments/products/filtered-diffuser-module)**\]): **Diffusers with ceiling-access filters have a 6" plenum box and are installed on top of the t-bar ceiling grid, replacing existing diffusers.   **Option 3: New Diffusers with Integrated Room-Side Accessible Filter (**[**Louvered Face Diffuser with Filter \[AMDC\]**](https://www.priceindustries.com/diffusers/products/smd-modular-louvered-diffuser)** and **[**Radial Vane Diffuser with Filter \[RVDC**](https://www.priceindustries.com/criticalenvironments/products/rvdc-radial-vane-diffuser-filter)**\]): **Diffusers with room-side accessible filters have a 6" plenum box and are installed on top of the t-bar ceiling grid, replacing existing diffusers. As the name implies, room-side replaceable filters provide convenient access to the filter from the room side for periodic filter replacement.  **Overhead Supply with Supplementary Filtration**  **Option 1: Portable Air Purification(**[**Room Air Purifier \[RAP**](https://www.priceindustries.com/terminalunits/products/rap-room-air-purifier)**\]):**The Price Room Air Purifier (RAP) improves indoor air quality with air filtration wherever and whenever you need it.   **Option 2: Filtered Exhaust Booster: **The booster unit is designed to drop into existing duct work and provide filtration to exhaust air before returning to the air handler.  **Option 3: Overhead Air Purifier (OAP): **The goal of the Overhead Air Purifier (OAP) is to filter room air through consistent air changes. The OAP is designed to be installed directly above any space and does not require modification to existing ductwork or other HVAC equipment.  **Overhead Supply with Supplementary In-Ceiling HEPA or ULPA Filtration **  **Option 1: Supply Puraflo with Return Grille**[**(Fan Filter Unit for Commercial Applications \[PURAFLO**](https://www.priceindustries.com/criticalenvironments/products/puraflo)**\]): **This configuration makes use of a standard return grille (like the Price 80 series) and a supply style Puraflo unit to draw room air in through the return grille and distribute the HEPA or ULPA filtered air to the space with a laminar airflow pattern.  ![](https://info.hoffman-hoffman.com/hs-fs/hubfs/image-png-Mar-31-2021-07-41-37-71-PM.png?width=172&name=image-png-Mar-31-2021-07-41-37-71-PM.png) **Option 2: Exhaust Puraflo with Supply DiffuserGrille **[**(Fan Filter Unit for Commercial Applications \[PURAFLO**](https://www.priceindustries.com/criticalenvironments/products/puraflo)**\]): **This configuration features an exhaust Puraflo unit and a standard supply diffuser (like the Price SPD) to draw room air in through the face of the Puraflo and distribute the HEPA or ULPA filtered air to the space with your desired throw characteristics.  **Displacement Supply, Filtered Return, and Room Filtration **  **Option 1: Ceiling Displacement**[**(Displacement Flow Ceiling Diffuser \[DFC**](https://www.priceindustries.com/displacement/products/dfc-displacement-flow-ceiling-diffuser)**\]): **A ceiling model DFC displacement diffuser can be installed into an existing ceiling grid removing the existing supply grille.  **Option 2: Ceiling Displacement with Fan Mixing Box: **Using existing ductwork, a fan mixing box with a MERV13 filter replaces the VAV terminal unit. this option requires ceiling mounted displacement diffusers (DFC), and a fan mixing box with a MERV13 filter for enhanced filtration of the recirculated air.  **![](https://info.hoffman-hoffman.com/hs-fs/hubfs/image-png-Mar-31-2021-07-43-34-99-PM.png?width=150&name=image-png-Mar-31-2021-07-43-34-99-PM.png)Option 3: Low Level Displacement with Fan Mixing Box (**[**1 Way Corner Displacement Diffuser \[DF1C**](https://www.priceindustries.com/displacement/products/df1c-rectangular-1way-displacement-diffuser)**\]): **Existing ductwork can be rerouted down from the ceiling and connected to the corner Displacement Corner Cabinet.
