Both refer to <strong>controlled environments<\/strong>, essential in industries where air purity and environmental conditions determine the quality of the final product.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Today we clearly explain the difference between a <strong>white room and a cleanroom<\/strong>, how they are classified according to the <strong>ISO 14644<\/strong> standard, and the role they play across different industrial sectors.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">What a cleanroom is<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">A <strong>cleanroom<\/strong> is an enclosed space where the concentration of suspended particles is controlled, along with other parameters such as temperature, humidity, pressure or airflow.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">These rooms are built following international classification standards (<strong>ISO 14644, GMP, FDA<\/strong>) that define the maximum permitted particle limits per cubic meter of air.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The term <strong>cleanroom<\/strong> is the more generic one and applies to any environmentally controlled space intended to protect sensitive processes or high-precision products.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">What a white room is<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">The term <strong>white room<\/strong> is more common in Spanish-speaking countries and is typically used to refer to a high-demand cleanroom \u2014 that is, one belonging to the <strong>lowest, most critical ISO classes<\/strong> (for example, <strong>ISO 5<\/strong> or <strong>ISO 6<\/strong>).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In this type of environment, design, filtration and cleanliness requirements are stricter:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Laminar airflows are used, minimizing turbulence.<\/li>\n\n\n\n<li>High-efficiency <strong>HEPA<\/strong> or <strong>ULPA<\/strong> filters are installed.<\/li>\n\n\n\n<li>Materials are completely smooth, washable and free of visible joints.<\/li>\n\n\n\n<li>Staff must follow sterile access and clothing protocols.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Therefore, although both terms can refer to the same type of installation, a white room usually implies a higher level of purity and environmental control. <strong>Think of the cleanroom as a standard operating room and the white room as a maximum-security isolation room.<\/strong><\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Comparison table: cleanroom vs. white room (technical highlights)<\/h4>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Characteristic<\/th><th>Cleanroom<\/th><th>White Room<\/th><\/tr><\/thead><tbody><tr><td>Definition<\/td><td>Environment with control of particles, temperature and humidity.<\/td><td>Ultra-clean environment, with strict control of particles and pressure.<\/td><\/tr><tr><td>Cleanliness level (ISO 14644)<\/td><td>ISO 7\u20138\u20139 (medium or basic levels).<\/td><td>ISO 4\u20135\u20136 (high or critical levels).<\/td><\/tr><tr><td>Common applications<\/td><td>Food, cosmetics, general electronics industry.<\/td><td>Pharmaceutical, biotechnology, microelectronics, research laboratories.<\/td><\/tr><tr><td>Air system<\/td><td>Turbulent or mixed flow.<\/td><td>Unidirectional laminar flow.<\/td><\/tr><tr><td>Air pressure<\/td><td>Moderate, may vary by zone.<\/td><td>Positive and constant to prevent contamination.<\/td><\/tr><tr><td>Equipment<\/td><td>Standard HEPA filters, technical furniture.<\/td><td>ULPA filters, antistatic materials, stainless steel and phenolic resin.<\/td><\/tr><tr><td>Main regulations<\/td><td>ISO 14644, basic GMP.<\/td><td>ISO 14644, advanced GMP, FDA.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">In short, <strong>every white room is a cleanroom, but not every cleanroom meets the conditions necessary to be considered a high-demand white room.<\/strong><\/p>\n\n\n\n<h4 class=\"wp-block-heading\">ISO 14644 classification: the particle threshold that defines the difference<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">The <strong>ISO 14644-1<\/strong> standard classifies <strong>cleanrooms<\/strong> according to the maximum number of particles per cubic meter. The lower the <strong>ISO<\/strong> number, the higher the degree of cleanliness.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>ISO

class=\"wp-block-heading\">Complementary regulations: GMP and FDA<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">In addition to <strong>ISO 14644<\/strong>, <strong>Good Manufacturing Practices (GMP)<\/strong> and <strong>FDA<\/strong> regulations define additional requirements in the <strong><a href=\"https:\/\/ingenic.es\/en\/pharmaceutical-industry\/\" data-type=\"page\" data-id=\"5826\">pharmaceutical<\/a><\/strong> and healthcare industry.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>These regulations govern aspects such as:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Frequency of air renewal.<\/li>\n\n\n\n<li>Microbiological control of surfaces and equipment.<\/li>\n\n\n\n<li>Staff clothing and access procedures.<\/li>\n\n\n\n<li>Periodic cleaning and validation of spaces.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">That&#8217;s why, when referring to a <strong>GMP white room<\/strong>, it means an environment validated under the strictest standards of purity and control.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Examples of cleanroom and white room use<\/h4>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>ISO 8 cleanroom:<\/strong> packaging or handling area for non-sterile products.<\/li>\n\n\n\n<li><strong>ISO 5 white room:<\/strong> research laboratory or

cosmetics or optical microcomponents.<\/li>\n<\/ul>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"wp-block-paragraph\">Each sector defines its own requirements, but all share the need to maintain controlled, safe and certified environments.<\/p>\n<\/blockquote>\n\n\n\n<p class=\"wp-block-paragraph\">Broadly speaking, the difference between a <em><strong>white room<\/strong><\/em> and a <em><strong>cleanroom<\/strong><\/em> lies in the level of environmental control and the type of process they are intended for, with <strong>white
