Moisture is released (dries out) from the humidification filters that have absorbed water, similar to the evaporation that occurs in everyday life, and therefore water vapor is not visible. Minerals in the water (hard water) do not enter the room but remain inside the unit. Oskar recommends replacing the paper humidification filters after 2\u20133 months of use.   <\/p>\n<p>A water droplet is so small that scale particles and bacteria cannot fit inside it.<\/p>\n<p>When the device is not in use, the water tank should be emptied to prevent biomass (bacteria\/algae) from forming in the residual water.<\/p>\n<p>With natural air humidification, airborne dust also sticks to the humidification filters.<\/p>\n<p>&nbsp;<\/p>\n<p><strong>Applications for natural air humidifiers:<\/strong><\/p>\n<p>Natural humidifiers are suitable for use both at home and in the office. At home, we recommend using a humidifier primarily in bedrooms, since maintaining adequate humidity is most important there, and Oskar humidifiers operate quietly and consistently. <\/p>\n<p><strong>Pros and cons of the Oskar natural air dehumidifier:<\/strong><\/p>\n<p><strong>+ Low <\/strong>noise level, minimal maintenance (filter replacement every 2\u20133 months), convenient for use with hard water (no white residue or dust).<\/p>\n<p>\u2014 The Oskar\u2019s humidification capacity is approximately 200 ml\/h\u2014less than that of more powerful humidifiers (e.g., the Oskar Big, approximately 500 ml\/h) \u2013 therefore, it is recommended for smaller rooms (up to 20 m\u00b2, with the door closed).<\/p>\n<p><strong>Technical Specifications<\/strong><\/p>\n<div id=\"product_tabs_description_tabbed_contents\">\n<div class=\"box-collateral box-description\">\n<div id=\"DescHide\" class=\"std\">\n<p>\u2013 Designed by Matti Walker (Switzerland)<br \/>\n\u2013 Water tank capacity: 3.5 liters<br \/>\n\u2013 Integrated hygrometer (40%, 45%, 50%, 55%, and Co)<br \/>\n\u2013 2 humidification filters and Water Cube<br \/>\n\u2013 2 fan speeds (I and II)<br \/>\n\u2013 Option to use essential oils<br \/>\n\u2013 Recommended room size: up to 20 m\u00b2, with the door closed (50 m\u00b3)<br \/>\n\u2013 Dimensions: 29 x 24.6 x 24.6 cm<br \/>\n\u2013 Humidification capacity: approx. 100 g\/h (I) and approx. 200 g\/h (II)<br \/>\n\u2013 Power consumption: 6\u201318 W<br \/>\n\u2013 Noise level: 26\u201339 dB(A)<br \/>\n\u2013 Weight: 3.1 kg<br \/>\n\u2013 Galvanized metal base<br \/>\n\u2013 Manufactured in China<br \/>\n\u2013 Certifications: CE, ETL, ROHS, WEEE  <\/p>\n<p>Winner of the Swiss air humidifier test for the 2011\/12 season (Kassensturz 11\/2012)!<\/p>\n<p><a href=\"https:\/\/www.airvitamin.ee\/wp-content\/uploads\/2019\/12\/Oskar_final.pdf\"><strong>USER MANUAL<\/strong><\/a><\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<h3 class=\"product-title product_title entry-title\">Stadler Form Oskar Natural Air Humidifier (Black)<\/h3>\n<div class=\"product-short-description\">\n<ul>\n<li>Very quiet (suitable for a bedroom)<\/li>\n<li>Recommended room size: up to 20 m2<\/li>\n<li>Options for Using Essential Oils<\/li>\n<li>Adjustable LED lighting<\/li>\n<\/ul>\n<\/div>\n","protected":false},"featured_media":42693,"template":"","meta":{"_acf_changed":false,"_seopress_titles_title":"Stadler Form Oskar Natural Air Humidifier (White)","_seopress_titles_desc":"Stadler Form Oskar Natural Air Humidifier: Very quiet, recommended for rooms up to 20 m\u00b2, option to use essential oils, adjustable LED lighting","_seopress_robots_index":"","_seopress_robots_follow":"","_seopress_robots_imageindex":"","_seopress_robots_snippet":"","_seopress_robots_primary_cat":"none","_seopress_robots_breadcrumbs":"","_seopress_robots_freeze_modified_date":"","_seopress_robots_custom_modified_date":"","_seopress_robots_canonical":"","_seopress_social_fb_title":"","_seopress_social_fb_desc":"","_seopress_social_fb_img":"","_seopress_social_fb_img_attachment_id":0,"_seopress_social_fb_img_width":0,"_seopress_social_fb_img_height":0,"_seopress_social_twitter_title":"","_seopress_social_twitter_desc":"","_seopress_social_twitter_img":"","_seopress_social_twitter_img_attachment_id":0,"_seopress_social_twitter_img_width":0,"_seopress_social_twitter_img_height":0,"_seopress_redirections_value":"","_seopress_redirections_enabled":"","_seopress_redirections_enabled_regex":"","_seopress_redirections_logged_status":"both","_seopress_redirections_param":"","_seopress_redirections_type":301,"_seopress_analysis_target_kw":""},"product_brand":[797],"product_cat":[944,946,945],"product_tag":[],"class_list":["post-42692","product","type-product","status-publish","has-post-thumbnail","product_brand-stadler-form","product_cat-air-humidifiers","product_cat-dust-free-humidification","product_cat-humidifiers-home-office","first","instock","taxable","shipping-taxable","purchasable","product-type-simple"],"acf":[],"_links":{"self":[{"href":"https:\/\/proair.ee\/en\/wp-json\/wp\/v2\/product\/42692","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/proair.ee\/en\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/proair.ee\/en\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/proair.ee\/en\/wp-json\/wp\/v2\/media\/42693"}],"wp:attachment":[{"href":"https:\/\/proair.ee\/en\/wp-json\/wp\/v2\/media?parent=42692"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/proair.ee\/en\/wp-json\/wp\/v2\/product_brand?post=42692"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/proair.ee\/en\/wp-json\/wp\/v2\/product_cat?post=42692"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/proair.ee\/en\/wp-json\/wp\/v2\/product_tag?post=42692"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
