What is the difference between Purple and Brown Ereada® mats?
PURPLE Ereada® mats feature magnetic pulsation (PEMF) and photon red-light technology, making them more advanced and multifunctional.
BROWN Ereada® mats are more classic in design and function and are similar to Richway products.
Ereada® mats larger than the Mini size have seven heat levels on the controller.
The Brown Mini mat uses a fully adjustable controller that displays temperatures from 30°C to 70°C.
Heat levels are as follows:
Level 1 — 86°F / 30°C
Used for negative ions and negative potential, as well as all-night low-heat sleep mode.
Level 2 — 98°F / 36°C
Low heat mode.
Level 3 — 110°F / 43°C
Low-medium heat mode.
Level 4 — 120°F / 49°C
Medium heat mode.
Level 5 — 133°F / 56°C
Medium-high heat mode.
Level 6 — 145°F / 63°C
High heat mode.
Level 7 — 158°F / 70°C
Highest heat mode.
Classic Brown Ereada® mats include the Negative Potential (N.P.) function. This system is considered one of the most effective methods of negative-ion generation. It uses a silver-fiber layer to create a high negative electrostatic potential (approximately –600 V DC), similar in concept to the Richway E.D.N.I. system.
PURPLE Ereada® mats in Compact Pro size and larger include:
- permanent static magnets (about 300 gauss) in the hip and leg area
- PEMF magnetic pulsation (about 400 gauss, 8–64 Hz) in the upper body zone
- photon red-light function (660 nm)
PURPLE mats do not include the Negative Potential function found in Brown Ereada® mats.
The PURPLE Mini mat includes static magnets and the photon red-light function but does not include PEMF.
PURPLE Ereada® mats also generate negative ions into the air, though typically in smaller amounts than Brown Ereada® mats with the high-voltage negative potential system.
In terms of gemstone content and total weight, PURPLE Ereada® mats of the same size are usually slightly heavier due to their additional components.
The maximum heat level of PURPLE Ereada® mats may feel slightly stronger, as magnetic pulsation can intensify the perceived heating effect when used together with crystal heat.
Using PEMF on a PURPLE Ereada® mat at the lowest heat level can feel similar to the Negative Potential function of Brown Ereada® mats or the E.D.N.I. function of Richway professional mats. However, the N.P. function is generally gentler. It typically runs for one hour and then shuts off automatically, which makes it more suitable for sleep.
PEMF operates in cycles, activating for about 20 minutes every 90 minutes when enabled. Although PEMF and N.P. may feel similar in effect to some users, they use different technologies and work in different ways.
PURPLE Ereada® mats also include photon red-light therapy, which some users choose for cosmetic or skin-care purposes.
Some customers sleep on amethyst mats using low heat settings. However, PEMF reactivating during the night may feel overstimulating for certain people, especially with the higher intensity found in PURPLE Ereada® mats. For this reason, PEMF is often preferred for daytime use.
If you choose to sleep on a PURPLE Ereada® mat, it is recommended to manually turn off the Photon function (which otherwise resumes every 4 hours) and PEMF after the first cycle. One cycle is usually sufficient. Personal preferences vary, and many users discover their optimal routine over time.
The surface of PURPLE mats is made from a breathable mesh fabric, which may result in slightly more noticeable stone pressure compared to the softer suede surface of Brown mats. However, all Ereada® mats are supplied with thick protective covers, which largely eliminate this difference in firmness.
