It ensures <strong>80% of water quality<\/strong>, well before chemical treatment products. Without the right filtration system, even the best chlorine in the world won&#8217;t guarantee crystal-clear water.  <\/p>\n<p>At <strong>Astro Piscines<\/strong>, we&#8217;ve been designing and installing custom filtration systems for swimming pools in <strong>Geneva<\/strong> and the canton of <strong>Vaud<\/strong> since 1974. Our expertise: perfectly dimensioning the pump-filter pairing to guarantee pure water, significant energy savings and silent operation. <\/p>\n<p>Discover our two essential components: filtration pumps and high-performance filters.[\/vc_column_text][vc_empty_space height=&#8221;5px&#8221;][vc_separator el_width=&#8221;80&#8243; css=&#8221;&#8221;][\/vc_column][\/vc_row][vc_row equal_height=&#8221;yes&#8221; css=&#8221;.vc_custom_1765347845690{background-color: #FFFFFF !important;}&#8221;][vc_column width=&#8221;1\/2&#8243;][vc_column_text css=&#8221;&#8221;]<\/p>\n<h2>How does pool filtration work?<\/h2>\n<p>[\/vc_column_text][vc_empty_space height=&#8221;5px&#8221;][vc_column_text css=&#8221;&#8221;]The principle is simple, but essential to understand. The water in your pool is drawn in by the skimmers (surface skimmers) and the bottom drain, then sent to the <strong>equipment room<\/strong>. There, it first passes through the pump that creates movement, then through the filter that retains impurities. The clean water is then returned to the pool via the discharge nozzles.   <\/p>\n<p>This cycle must be repeated several times a day to ensure that <strong>100% of the water volume<\/strong> is filtered. This is called <strong>filtration time<\/strong>, and is generally calculated as follows: water temperature divided by 2. At 26\u00b0C, the daily filtration time is approximately 13 hours.  <\/p>\n<p><strong>A properly dimensioned system guarantees :<\/strong><\/p>\n<ul>\n<li>Effortless transparent water<\/li>\n<li>50% reduction in chemical consumption<\/li>\n<li>Substantial electricity savings thanks to modern pumps<\/li>\n<\/ul>\n<p>[\/vc_column_text][\/vc_column][vc_column width=&#8221;1\/2&#8243;][vc_single_image image=&#8221;17509&#8243; img_size=&#8221;full&#8221; alignment=&#8221;center&#8221; css=&#8221;&#8221;][\/vc_column][\/vc_row][vc_row equal_height=&#8221;yes&#8221; css=&#8221;.vc_custom_1765347845690{background-color: #FFFFFF !important;}&#8221;][vc_column width=&#8221;2\/3&#8243;][vc_empty_space height=&#8221;5px&#8221;][vc_column_text css=&#8221;&#8221;]<\/p>\n<h2>Filtration pumps: The heart of the system<\/h2>\n<p>The pump is the engine of your hydraulic circuit. It draws in the water and pushes it through the filter with sufficient pressure to ensure optimum flow. An undersized pump = cloudy water. An oversized pump = a skyrocketing electricity bill.   <\/p>\n<p>At Astro Piscines, we&#8217;ve chosen <strong>Pentair<\/strong>, the world leader in swimming pool equipment. Why did we choose Pentair? For three essential reasons:  <\/p>\n<h3>Energy savings<\/h3>\n<p>Our <strong>variable-speed<\/strong> pumps like the Ultraflow VS2M consume up to <strong>70% less electricity<\/strong> than a traditional single-speed pump. Over a full season, that&#8217;s several hundred francs saved on your bill. <\/p>\n<h3>Silent operation<\/h3>\n<p>At low speed, the pump becomes almost inaudible. No more constant whirring to spoil your moments of relaxation by the water. Your neighbors will thank you too.  <\/p>\n<h3>Proven reliability<\/h3>\n<p><strong>Sta-Rite<\/strong> and <strong>Ultraflow<\/strong> models are renowned in the trade as &#8220;puncture-proof&#8221;. Some Pentair pumps have been in operation for over 20 years without major failure. It&#8217;s a lasting investment.[\/vc_column_text][vc_empty_space height=&#8221;15px&#8221;][vc_btn title=&#8221;Discover our Pentair filtration pumps&#8221; shape=&#8221;square&#8221; color=&#8221;primary&#8221; css=&#8221;&#8221; el_class=&#8221;mon-bouton-bleum&#8221; link=&#8221;url:https%3A%2F%2Fwww.astro-piscines.ch%2Ffr%2Fequipements-piscine-geneve-vaud-pompe-chauffage-couverture%2Ffiltration-de-piscine%2Fpompe-piscine-silencieuse-economique-geneve-vaud-pentair%2F|title:Pompe%20Piscine%20Silencieuse%20%26%20%C3%89conomique%20%28Gen%C3%A8ve%20Vaud%29%20%7C%20Pentair%20Meta|&#8221;][vc_empty_space height=&#8221;15px&#8221;][\/vc_column][vc_column width=&#8221;1\/3&#8243;][vc_single_image image=&#8221;17518&#8243; img_size=&#8221;full&#8221; alignment=&#8221;center&#8221; css=&#8221;&#8221;][\/vc_column][\/vc_row][vc_row full_width=&#8221;stretch_row_content&#8221; equal_height=&#8221;yes&#8221; content_placement=&#8221;middle&#8221; bg_type=&#8221;bg_color&#8221; bg_override=&#8221;full&#8221; css=&#8221;.vc_custom_1765347941866{margin-top: 50px !important;margin-bottom: 50px !important;}&#8221; bg_color_value=&#8221;#F5F5F5&#8243;][vc_column width=&#8221;1\/3&#8243; css=&#8221;.vc_custom_1772619865574{background-image: url(https:\/\/www.astro-piscines.ch\/wp-content\/uploads\/2026\/03\/Fitration-piscine-en-Suisse-par-Astro-Piscines-scaled.png?id=17568) !important;background-position: center !important;background-repeat: no-repeat !important;background-size: cover !important;}&#8221; offset=&#8221;vc_col-lg-6 vc_col-md-6 vc_hidden-xs&#8221;][\/vc_column][vc_column width=&#8221;1\/3&#8243; offset=&#8221;vc_hidden-lg vc_hidden-md vc_hidden-sm&#8221;][vc_single_image image=&#8221;17569&#8243; img_size=&#8221;full&#8221; css=&#8221;&#8221;][\/vc_column][vc_column width=&#8221;1\/3&#8243; offset=&#8221;vc_col-lg-6 vc_col-md-6&#8243;][vc_empty_space height=&#8221;5px&#8221;][vc_column_text css=&#8221;&#8221;]<\/p>\n<h2>Filters: The lungs that purify water<\/h2>\n<p>[\/vc_column_text][vc_empty_space height=&#8221;5px&#8221;][vc_column_text css=&#8221;&#8221;]<\/p>\n<p class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\">The filter retains suspended particles: dust, pollen, microscopic algae, sunscreen residues, hair&#8230; The more efficient the filter, the more crystal-clear the water, and the fewer treatment products you need. <\/p>\n<p class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\">At Astro Piscines, we&#8217;ve made a radical choice: to <strong>offer only the best<\/strong>.
