eCAPR FAQs - General

What is the MAXAIR eCAPR?

eCAPR is a uniquely designed loose-fitting Powered Air Purifying Respirator (PAPR) that sets the standard for the future of respiratory and contact protection.

This NIOSH-approved integrated helmet design provides complete air filtration without the bulk, as we have eliminated the need for a typical hose attachment used for many PAPR models.

Depending on the complete system selected (i.e., cuff, shroud, hood, or hard hat), MAXAIR’s eCAPR can provide respiratory, contact, fluid, head and/or eye impact protection.

  • Cuff Systems: The most cost-effective, easiest to don/doff
  • Shroud Systems: Full 360º head and neck protection
  • Hood Systems: Full 360º head and neck protection, high fluid resistance (ASTM 1671)
Are all MAXAIR eCAPR Systems NIOSH approved?


Refer to the Home page "View NIOSH Approvals" and "Go to" for more information.

Note that all regulatory approvals for the MAXAIR Brand of products are held by Syntech International, Inc., the exclusive manufacturer of all MAXAIR Brand products.

Do I need to be fit tested?

No, OSHA does not require fit testing for positive pressure loose-fitting PAPRs, including eCAPR.

Can I wear eCAPR if I have a beard or wear glasses?

Yes, all configurations fit users with facial hair and eyeglasses. No additional attachments are needed.

Can multiple users use one eCAPR?

Yes. Please ensure you clean the unit and replace both the comfort strips and face or head covers between uses.

What system configurations are available?

There are two MAXAIR Base Systems to choose from.

Each base system consists of a helmet, a battery, a battery belt, and a charger. The specific product numbers are listed below.

The two Base Systems, together with Peripherals (necessary items depending on the final Complete System desired), plus your choice of disposables (Head Covers), plus any desired Accessories make up Complete Systems.

The Complete Systems are Cuff, Shroud, Hood, or Hard Hat based.

What is the proper configuration for various applications and settings?

Cuff configurations are the primary choice where contact and fluid contamination are not of major concern, as your neck and parts of your head are exposed, and when lowest cost-per-use is required.

Shroud configurations are usually recommended over Cuffs when contact and fluid contamination are of greater concern.

Hood configurations offer the highest tier of protection, a single piece integrated filter and full 360 degree contact protection shroud, and low risk of self-contamination by minimizing system decon time.

What areas / applications can I use the MAXAIR eCAPR for?

MAXAIR eCAPR Systems are specifically designed for Industrial applications and situations and can be configured with appropriate face/head covers to provide protection against airborne particulates and varying degrees of contact/splash, fluid, and head and/or eye impact in a broad range of industries, including but not limited to the following.

  • Woodworking, Construction
  • Powder Coating
  • Landscaping
  • Agriculture, Plant and Animal
  • Cannabis
  • Laboratory Research
  • Textile, Pulp, Paper
  • Materials, Ore Mining
What is the noise level of the system?

The average decibel level of eCAPR is typically below 69 db, lower than most conventional PAPRs.

Where can I find donning, doffing and other detailed information about eCAPR configurations?

You may view and download more details about eCAPR and its configurations from the Resources section, particularly from the User Instructions System Manual (User Instruction Manuals).

What material are the disposable cuffs, shrouds, and hoods made from?

Our Cuffs, Shrouds and Hoods are all made from polypropylene material or blends, or polyurethane.

What material are the lenses made from?

The lenses are made from polycarbonate and PETG (DLC Cuffs).

Is the lens fog proof?

Yes, eCAPR channels airflow down the inside of the lens, maintaining a fog-free lens and providing a cooling effect for the user.

eCAPR FAQs - Integrated Helmet

Without a hose attachment, where does eCAPR get its air supply?

The integrated motor fan in the top rear of the helmet draws in ambient air through its filter. The filtered air is channeled inside the helmet and flows down between the lens and the user. This provides resistance-free breathing, automatically defogs the lens, and exhausts exhaled CO2 while providing a cooling effect for greater comfort.

How much airflow am I getting with eCAPR?

The eCAPR air flow is set to approximately 300 lpm for ultimate user comfort.

What do the Safety Status LEDs indicate?

The yellow LED indicates a low airflow condition. This means the system is nearing a point when it won’t be able to maintain the desired airflow. If this light is on, we encourage you to check the filter to see if a replacement is necessary.

The green and red LEDs indicate the amount of charge remaining on the eCAPR.

If red and yellow LEDs are lit, both the battery and the filter need to be checked for change out.

How does MAXAIR accommodate different users’ head sizes?

MAXAIR’s helmets are equipped with a universal liner/headband and a ratchet knob that can you can easily adjust.

The headband allows for both height and circumferential size adjustments.

eCAPR FAQs - Filters

What are the eCAPR System Filter configurations?

Always be aware that MAXAIR Filters are for airborne particulates only; MAXAIR Filters are not for use where gases and vapors need to be filtered.

MAXAIR Cuff and Shroud Systems use individual Filter Caps and Filter Cartridges; Hood Systems use a filter that is integrated into the top of the Hood.

MAXAIR eCAPR System Filters are classified by NIOSH as PAPR HE.

Cuff and Shroud Systems Filter:

The 2167-10 XP filter cartridge are convenient snap-on/snap-off filters for use with the MAXAIR eCAPR Cuff and Shroud System configurations.

  • When used with Cuff Systems they are APF of 25 per OSHA[1].
  • When used with Shroud Systems they meet OSHA’s requirements for APF of 1,000 per our engineering test data.

[1] Page 14, Table 1., Note 4

Hood Systems Filters:

eCAPR Hoods have a PAPR HE XP filter integrated into their top. Class HE Hoods come with a NIOSH required HLF (Heavy Loading Filter). eCAPR Hoods have APF of 1,000.

Note that All MAXAIR Hoods may be worn with an optional High Fluid Resistant Filter Cover Cap for maximum fluid protection of the filter area.

How often does the filter need to be changed?

Depending on the frequency of use and industrial application, we recommend changing your eCAPR filter every 6 to 12 months, whenever the yellow LED Safety indicator is lighted during use, and whenever the filter integrity is compromized.

Can MAXAIR Filters be cleaned and reused?

No. Please discard your MAXAIR filter after the yellow LED light is triggered or after 6 to 12 months of use, or whenever the integrity of the filter is compromized.

Will the filters withstand water?

MAXAIR System filters are not intended to be exposed to water. If you anticipate light water exposure, we recommend using a shroud configuration with a Filter Cover Cap or a hood configuration with a High Fluid Resistance Filter Cover Cap.

Is there a protective cover that can be placed on top of the helmet for added protection?

Yes, all eCAPR configurations have a filter cover that protects the filter or filter cartridge.

The FCC (FIlter Cover Cap) is for Cuff and Shroud systems.

The Hard Hat is for Cuff and Shroud Hard Hat systems.

The HFR-FCC (High Fluid Resistance Filter Cover Cap) is for Hood systems.

Does MAXAIR’s eCAPR system filter out gases and vapors?

No, our filters are for airborne particulates only.

eCAPR FAQs - Batteries, Belts, Chargers

What is the standard MAXAIR System battery and how long does one battery charge last?

The 2500-36TSC Lithium-Ion Battery is the primary battery included in system configurations. It typically provides 4 to 5 hours of continuous use per full charge, ideal in a low particulate density concentration, filter loading environment.

The 2500-37TSC Lithium-Ion battery is an alternative for all systems. It typically provides 6 to 7 hours of continuous use per full charge. It is the same size and weight as the 2500-36TSC.

How many times can the battery be recharged?

The battery can be recharged between 450-500 times (also known as “full charge cycles”). A cycle is defined as a complete discharge and recharge.

Partial cycle charging is safe and reliable with Lithium Ion batteries. Partial cycles are additive to make up complete cycles when estimating the number of charging cycles to expect from the useful life of a battery.

NOTE: Thoroughly review the MAXAIR Ensure Readiness Program for proper care and use of MAXAIR Batteries. (Refer to the Resources section, Literature, Technical Bulletins, Ensure Readiness Program.)

How long does it take to charge the battery?

The 2500-36TSC Lithium-Ion battery takes approximately 4 to 6 hours to charge completely. The 2500-37TSC requires approximately 5 to 7 hours.

Do NOT leave batteries on the charger after they are fully charged, as this may adversely affect the battery over time.

How long can I leave the battery on the charger?

Do NOT leave batteries on the charger after they are fully charged and the Charger LED turns Green. There is no practical benefit to leaving a MAXAIR Lithium Ion Battery connected to a MAXAIR Charger after it is fully charged. Leaving batteries on chargers any longer than a maximum of 8-10 hours only increases risk of something between the mains power source and the battery to go wrong and adversely affect the battery. Once the Charger Green LED turns on, disconnect the Battery from the Charger.

NOTE: Thoroughly review the MAXAIR Ensure Readiness Program for proper care and use of MAXAIR Batteries. (Refer to the Resources section, Literature, Technical Bulletins, " Ensure Readiness Program").

If I don’t use the system on a regular basis and only use it for emergency preparedness, how often does the battery need to be maintained?

Upon initial purchase, the battery is delivered and can be stored “as is” (at about 50% of full charge) and will provide 2-3 hours of use without being charged. Thereafter, we recommend you recharge the battery at least annually or bi-annually. Refer to the User's Instructions included with each Helmet shipment for details about intermittent use and long-term storage.

NOTE: Thoroughly review the MAXAIR Ensure Readiness Program for proper care and use of MAXAIR Batteries. (Refer to the Resources section, Literature, Technical Bulletins, Ensure Readiness Program.)

Do you have a belt to hold the battery?

Yes, a belt is supplied with all Base Systems and is available for purchase as an add-on/replacement.

Three belts are available, 2000-76 rayon, 2000-77 cleanable medium length, and 2000-78 cleanable long length.

Do you have a gang charger?

A 6-Gang Charger, (2602-06), is available and includes six 2600-02 chargers clipped on a single bracket. It also includes wall mounting hardware.

A 6-Gang Charger Bracket, the 2602-06B, is available for use with up to six existing 2600-02 chargers. A single bracket-to-wall power cord and wall-mounting hardware are included. The single chargers are not included.

eCAPR FAQs - Maintenance and Cleaning

How do I clean my eCAPR?

For everyday cleaning of your eCAPR, we recommend using a clean, damp cloth with a mild application of skin-friendly soap for the entire system.

For deeper cleaning, MAXAIR recommends using one of the following options (refert to the Literature section, Technical Bulletins).

  • PDI Super Sani-cloth Germicidal Disposable Wipe, Q55172
  • Clorox Healthcare Hydrogen Peroxide Cleaner Disinfectant, CLO30825
